I'll have to wait 'til I see them in person to decide what I'm gonna do. Most of us aren't fans of "action features" really, so the firing blasters and slashing lightsabers on these figures may be somewhat of a turn off. Not to mention that most of us probably won't want to actually "play the game" with these things either, beyond just a few random targeting practice sessions.
So these will live or die based likely on their "collectibility" with the more adult crowd, I'd imagine. If they're nicely detailed, have a good range of characters, are affordable, and aren't too much of a headache to collect (exclusives, pack-ins, etc), then I think they'll do OK. But if WOTC mostly tries to market them as a game for the younger kids, then they might be in trouble...
I probably won't buy the ROTS ones, but if an OT series comes out later on, I'll definitely be interested.
