So, let's guess the most likely NEW ships to feature in the game. (no Legends ships here)
REPUBLIC:
-
Eta-2 Actis-class interceptor -
BTL-B Y-wing starfighter - Clone Z-95 starfighter (dual torpedo slots, shield and faster speeds can make it different of the Torrent. With the clones Killer , Warthog and Hawk as named pilots)
-
Alpha-3 Nimbus-class V-wing starfighter -
Low Altitude Assault Transport/infantry(LAAT/i) - maybe in their "space" variant. (too iconic to not feature in game) - Theta-class T-2c shuttle , Nu-class transport , or some other shuttle (there are plenty) OR
- J-type Star Skiff (just imagine how beautiful this would look on the table) - with some possible shenanigans with the Handmaidens
- LAAT/le gunship (alternative for a cheap shuttle/gunship - also used by the Empire)
- G9 Rigger-class freighter (ungainly ship, but kind of "important" in the Clone Wars series)
SEPARATISTS:
-
Droid tri-fighter - Rogue-class starfighter (maybe with Scum version too)
-
Nantex-class territorial defense starfighter -
HMP droid gunship(now in The Mandalorian's trailer !) - Sheathipede-class transport shuttle
-
Jango's Slave 1 - Zenuas 33 Umbaran starfighter (obscure, but looks super cool - and may have some movement shenanigans)
- Ginivex-class fanblade starfighter (weird and ugly, but with Ventress pilot)
- YV-865 Aurore-class freighter (there is a Scum - Mining Guild - version too, as seen in Rebels)
-
Techno Union fighter(really nothing special on this one) - NovaSword Space Superiority Fighter (was Legends but it's - timidly - coming back to canon)
-
Scarab-class Droid Starfighter(same as NovaSword) -
Tempest Zero(same as NovaSword, but even more obscure)
SCUM:
- Gauntlet fighter (almost into epic size, but mechanically fits better in the large base)
- SS-54 assault ship
- Pirate "ugly" starfighters from The Resistance series
- Pirate "ugly" shuttle from The Resistance series
- Aphra's heavily modified Bellicose-class Heavy Lifter ( Ark Angel I )
- Razor Crest from The Mandalorian series ( how the heck this is not in the game yet?! )
- The other ship in The Mandalorian teaser, firing at the Razorcrest. Here it is , and it's gorgeous! " Bounty Hunter Fighter " (I hope it has a more technical name, tough)
- The totally-not-a-Rogue-Class-Starfighter-variant unnamed "gunship" , seen briefly in The Mandalorian's chapter 6. It's so similar that I wouldn't mind if it was a configuration of the more famous starfighter .
- Guavian Death Gang ship (from The Resistance's 2nd season). More pics here . Oh, it was also in Ep. VII
- New droid racer ship from 2nd season of The Resistance - needs a mechanic for "landing" on another fighter
- Dalkor Dagger from The Resistance series (piloted by the bounty hunter Ax Tagrin )
- Meson Martinet , hinted in Ep. XIII but shown better in The Resistance
- Aka'jor-class shuttle (a little too obscure?)
EMPIRE:
-
TIE/rb heavy starfighter "Tie Brute" -
Outland TIE , in The Mandalorian(just a TIE Fighter with folding wings for landing) - TIE Command Shuttle (the real TIE Shuttle, saw very briefly in ESB , recently unveiled in book)
- Delta-class Shuttle (awkward model and too similar with the Lambda in role?)
- Auto-fighter / TIE Droid (back from the depths of Legends!)
REBELS:
- YT-2000 , now (new) canon!
- S-161 XL (title: Stinger Mantis ) from the game The Fallen Order. Not exactly Rebel (kind of former Republic? Scum?), but there aren't many options...
- BT-45D U-Wing ( Ryder Azadi's U-Wing from Rebels is so cute!)
RESISTANCE:
- T-85 X-Wing (with an exclusive mod that gives cloaking?)
-
Fireballand other "racing" ships from The Resistance series ( Black Ace is awesome). There are at least 6 other ships in the Ace Squadron and oh, they would look awesome in a X-Wing spin-off about racing (totally compatible with the main game). - Y-Wing BTA-NR2 (yay! Y-Wings for everybody!).
- Venisa Doza's modified T65B X-Wing from 2nd season of The Resistance. How about an X-wing with attack 2 , jam action, missiles, torpedoes, cannon, maybe some illicit and a few mod slots?
- Resistance B-Wing (we don't know much about this ship, except for the fact it's very ugly).
- WTK-85A transport (title: Bestoon Legacy ) - is it Scum? was this ship originally piloted by Rey's parents? Well, has at least one First Order (Ochi) and one Resistance (Poe) pilot. More info released.
-
Star Commuter 2000 - civilian shuttle used in Star Wars The Resistance (and in Rebels).Probably unnarmed. - I-TS from Galaxy's Edge.
- A lot of ships in the background of the big (space?) battle in Ep. IX.
FIRST ORDER:
-
First Order TIE Baron -
Xi-class light shuttle - TIE Whisper Starfighter (a lot like the FO Special Forces TIE - turret and all - with the Jam action, maybe more agile and with 1 less shield?)
- TIE Whisper Interceptor (from the Ep. IX traile r) - this is Kylo's TIE Whisper, with wings of the TIE/vn (it has a turret and the same rear window of the TIE/sf - maybe indicating a gunner?). 3 frontal attack + "Heavy Weapons Turret" = wow!
- TIE Dagger / Sith TIE Fighter (could be Attack 2 + cannon slot to differentiate it from the other FO TIEs)
- First Order TIE Bomber (from 2nd season of The Resistance and comics - looks boss and would be useful for the FO)
- Drone X-Wing (from The Resistance show)
- Oubliette-class transport , title: Night Buzzard (the ship of the Knights of Ren in Ep. IX).
- Droid Orbital Probe (wow, this could be really unique). More info here . And there is another: Spider Probe Droid .
-----------------------------------
Huge ships (including some more obscure* designs)
CIS:
- Hardcell-class Battle Refit (too big for current Epic)
- Automated Droid Deployment Station* (how cool would be that?)
- Trident-class assault ship (this one is quite unique!)
REPUBLIC:
- Consular-class Space Cruiser (with Radiant VII title)
- Paladin-class Corvette* (Most impressive! In Legends, Hondo salvaged the Crucible so... is it possible for the Scum faction?)
- CSS-1 Corellian Star Shuttle
REPUBLIC/REBELS:
- Hammerhead Corvette (with several canonical titles available)
REBELS:
- Braha'tok-class gunship* (maybe also Scum?)
- DP20 frigate* (also used by the Republic)
RESISTANCE:
- Modified Raider-II class corvette (retrofitted Corvus from Battlefront II)
- Many, many ships in the final "space" battle in Ep. IX.
EMPIRE/FIRST ORDER:
- Carrion Spike* (there is even a possible version for the Republic).
