Earlier this week Marvel sent out the cover to Avengers vs. X-Men #0, which kicks off their big round-robin crossover by Brian Michael Bendis, Jonathan Hickman, Jason Aaron and a slew of other big-name creators.

The cover they sent out by Frank Cho has a fairly large "A vs. X" logo covering up some of Cho's artwork, so if you're curious to see what -- and who -- is under the logo, Cho has shared the logo-less artwork on his blog. Hey look, it's Ultron!

The #0 issue by Bendis, Aaron and Cho comes out in March.
