I'm definitely glad we're getting some new stuff so quickly together. I do wish we'd get a good Alien Anthology, though. Those were always my favourite and most-used books from the previous editions and I'm not a fan of converting if I don't have to.
Rodney's said The Plan (tm) is to have a book every 2-3 months once they got going. Though the saga of delays in the Force Unleashed video game played havoc with that late last year and early this year.
Still, this year we get two era books (
KotOR and
Force Unleashed), a class book (
Scum and Villainy), and two general books (
Starships of the Galaxy and
Threats of the Galaxy). Next year is starting off with another two era books (Clone Wars and Legacy), but we don't know what's on the summer or fall schedule yet.
My guess on the future plans are
Era books: NJO and the Rebellion era the major ones left (Clone Wars should cover the prequel era well enough), though they might do something in the time between KotOR and the prequels.
Class books: It's easy to see follow-ons to
Scum and Villainy for scouts, soldiers, nobles, and Jedi.
Generalist books: The obvious ones here are your aliens book and an arms and equipment guide.
