*** UPDATE ***
Unfortunately this cover was never made. I guess Marvel.com made a mistake advertising a variant cover by Joe Madureira. Sigh... Guess We'll have to wait for Savage Wolverine #8 and Inhumans.
*** END UPDATE ***
The Marvel comic solicitations for September 2013 were just released and I've discovered that Joe Madureira will be drawing a variant cover to X-Men: Battle of the Atom #1. Hopefully we'll see the artwork soon! For now check out the inks to Savage Wolverine issue #8's cover and his X-Men #1 variant cover without the typography.
