Only thing I am worried about is that this is remanants of the cancelled Marvel Universe Online with a new name. Not that it couldnt be good though.

Confirmation of the project's cancellation arrived on February 11, 2008, although rumors of the possible cancellation had existed since at least November of the previous year. Shane Kim, the head of Microsoft Games Studios, stated in an interview that the cancellation was primarily due to the competitive market for subscription-based MMOs, and that while one current MMO was successful, "everything else wouldn’t meet our level or definition of commercial success".
Cryptic Studios have since announced that they are working on Champions Online, another superhero-based MMO
