The Specializations seem a bit odd to me. Charmer, Gambler, and Gunslinger all feel like more specific versions of the Scoundrel to me. I hope the overlap isn't too much, and I hope they still leave a solid role for the Scoundrel.
Was thinking much the same myself.
The Scoundrel already covers the "being charming and conniving" and "good with a blaster" aspects pretty well
Charming & Conniving: Convincing Demeanor and Natural Charmer talents, as well as Charm and Deception as a bonus career skills.
Good with a Blaster: Quick Draw, Quick Strike, Rapid Reaction, and Side Step talents (all handy things for a gunfighter) as well as Cool and Ranged (Light) as bonus career skills. Also got Soft Spot for added damage potential using one of the Smuggler's generally preferred characteristics (Cunning) and ranks of Toughened to further help combat survivability.
That and Charmer could also considered part of the Gambler's portfolio as well, though with Charmer I guess it could depend, particularly if they incorporate some of the new talents from the Performer spec, like Distracting Behavior, though again it could be something added to the Gambler just as easily (think Maverick from the Mel Gibson movie of the same name).
I was kinda hoping for a spec to allow a Smuggler to make their own "personal modifications" to a transport, such as what Han claimed about the Falcon in ANH after Luke called it a piece of junk. In effect, a spec to let Smugglers treat the party's ship as their own personal hot-rod.
As for new ships, I'm really hoping the VCX-100 (aka The Ghost from Rebels, though sans Hera's many modifications) makes an appearance. I'm hoping that this book offers a bunch of non-CEC ship models, as there's plenty of other ship manufacturers other than CEC and I'd like to see some of those vessels get covered rather than getting even more YT-series knock-offs.
