Where did this come from? Is it confirmed anywhere?
The question is this: What, realistically, can they put out that will excite folks the way the first few books did?
Largely covered, actually. Respectively:I guess there are also a couple of Era books they still haven't done: The New Republic Era, the New Jedi Order, and the era from the "Legacy of the Force" novel series.
Vehicles? Spacestations? Adventures? "The Definitive Guide to Mandalorians"?
Well, it's official. The Unknown Regions will be the last Star Wars RPG book WotC puts out. It's not just the end of Saga Edition. It's the end of WotC Star Wars all together - they've chosen not to renew their license.
