Interesting premise, plus doesn't seem to be held back by some other Xmen media, plus adding characters to canon seems like they have a lot of freedoms with the license, which is great, since we saw that DC got a good game (now a series) from Rocksteady in the form of Arkham Asylum due to liberal use of the Batman and DC license.
It's certainly the only XMen/Marvel game I've ever been interested in or willing to follow up on
