Do we think the Xbox 720 will offer a real MMO experience?

I was excited for the Xbox 360 and what it meant for online play. Age of Conan was supposed to come to the 360, and the PS3 has DC Universe and the Eve Online\Dust 514. I guess the greater question is, will Microsoft allow it.

I guess I am at the point where I want to play current games and don't know if I should hold out for the next Xbox or buy a new PC. There are so many great things happening on the PC right now, and it's not all about the graphics. I would love to see the next Xbox open up to developers a little bit more then they have.
