I figure this is a little early but as we know the contents of Waves 1 and 2 we can start making some educated guesses. We know that the wave 1 contents are:
Imperial: 3 Rebel: 4
Gladiator Star Destroyer (Small) Cr90 (Small)
Victory Star Destroyer (Medium) Nebulon-B Frigate (Small)
Imperial Squadron pack (Squadron) Assault Frigate MK II (Medium)
Rebel Squadron pack (Squadron)
And for wave two we have:
Imperial: 2 Rebel: 2
Imperial Star Destroyer (Large) Mon Calamari Cruiser (Large)
Imperial Raider (Small) Mon Calamari Frigate (Small)
Shared: 1
Rouges and Villains (Squadron)
Therefore we have for the Imperials 2 Small ships, 1 Medium ship, and 1 Large ship. The Rebels have 3 Small ships, 1 Medium ships, and 1 Large ships. And they both have access to 8 potential "squadron units", counting each of the Rouges and Villains ships as an available squadron. Then taking out the ships included in the core set we see that for wave 1 we have 4 expansions and wave 2 gives 5 more expansions. So my suggestion for wave 3 would be:
Imperial:
Dreadnaught-class Heavy Cruiser (Medium)
The ship could serve to be an option to Imperial fleets not having all of their guns focused entirely in the front arc. It could also be similar to the Gladiator in that it could be a little more maneuverable.
Interdictor-class Star Destroyer (Large)
This ship would be cheaper than an ISD with more of a focus on support roles maybe being able to reduce enemy ship speeds or have good options for defense, maybe having the evade token to represent the gravity fields disrupting missile and torpedo fire.
Imperial Support Craft (Squadron)
1: Decimator
It could act as another ship similar to the Rouges and Villians pack, mostly think it should be there to actually have an Imperial ship.
2: Lambda Shuttle
It could be used as a support craft to probably extend the reach of your ship's squadron commands.
3: Tie Defender
Keep them as the best fighters from lore, maybe giving them escort and a natural Brace defense token.
4: Alpha-Class Star Wing
Another bombing option for Imperials.
Rebel:
Mon Calamari Liberty Cruiser (Large)
Basically to have the standard Mon Cal cruiser there.
DP20 Frigate (Small) aka Corellian Gunship
Rebel heavy hitter for the small ships, probably make it so that they want to speed in fire a lot of black dice then run away before getting fired back in return.
Rebel Support Craft (Squadron)
1. GR-75 Transport
Rebel support craft.
2. Ghost/VCX-100 Light Freighter
Another option, also to give symmetry to the Decimator.
3. E-Wing
The Rebel high end fighter. Though something better may work.
4. Z-95
Cheaper Rebel squadron, maybe keeping escort but losing the bomber keyword.
