I beta tested TOR for a little while, and if you like MMOs you will probably enjoy it. I hoped I would, even though I'm not into MMOs, but I really didn't, so I stopped testing. It looks good though, for an MMO. It just isn't my thing. I wanted it to be, particularly when there were Jedis all around me fighting with their light sabers, and the voice acting was well done... but it was still ultimately an MMO. I do hope it works out for them. APB was an unparalleled mess. I would hate to see that happen to Bioware.
As for ME3, I'm confident it will do fine. The Mass Effect developers already had to deal with the backlash of revamping their game to a more FPS style battle, and they weathered that storm well, much better than DA2 did, that's for sure. Everything I'm reading says they won't be changing things up that much this go around, and it sounds like they are planning some really interesting stuff with the storyline and how everything ties in to your past choices. I think fans that weren't completely turned of by ME2 already, are likely going to be very pleased with the final installment.
