Midtown Comics have shown sketches for their J Scott Campbell variant cover triptych for All New X-Men #1, Uncanny Avengers #1 and Avengers #1, the latter of which gives some idea of the central cast for the Avengers Marvel NOW.comic. And it looks like we have Spider-Man, Black Widow, Hulk, Iron Man and Hawkeye. But of course Jonathan Hickman is promising a team of eighteen, so plenty more to come.
Hmm. Maybe we'll find out next week.
