If bioware is as smart as I hope they are, then they'll bring a little something to this one. Make an MMO with actual strategy when you fight, and a level cap that isn't insanely long to reach.
Also, I bet they could put in a cinematic story that would rival that of the games. I mean, Bioware masters in the nuances of the story, which could probably be implemented in an MMO just as effective as in a console game.
