Come on Lucas Arts give us Focom II
Yeah, that'd be awesome but I don't think they'll do it. They probably feel that they got burned a little once and won't want that to happen again. They'll probably just want to play it safe.
IMHO, I don't think Lucasarts will be developing any more SW games themselves - they'll probably outsource all development to more accomplished gamemakers. Gone are the days when you could simply shoot a laser at a cheesy-looking Tie Fighter and make everyone ooh and ah. Everyone expects UT-Max Payne-MOH sort of quality in a game (and there's nothing wrong with that).
Honestly, I doubt Lucasarts will delve into the 3D-strategy arena again - it's just much safer for them to develop tried-and-true genre games like GB. It's a major shame because the SW license is incredibly ripe for ground-based 3D combat.
