A while back, Marvel released previews of the Marvel vs. Capcom: Infinite variant covers for a number of their books. Since then however, more previews for these variant covers have been released.
The covers in question are for the Amazing Spider-Man #31, the Avengers #10, Doctor Strange #24, Generations: Hulk #1, Generations: Unworthy Thor & Mighty Thor #1, I Am Groot #20, Invincible Iron Man #10, Mighty Captain Marvel #8, Mighty Thor #22, Rocket #4, Secret Empire #8, Spider-Man #19, and Venom #153. With these previews, there are only a few Marvel vs. Capcom: Infinite variant covers that have yet to be revealed.

The issues with these variant covers are all supposed to hit this coming August. Meanwhile, Marvel vs. Capcom: Infinite launches on PlayStation 4, Xbox One, and PC on September 19.
