Updated with more.
Seeing how Diamond released the titles for Marvel's June 2011 solicits and seeing how one was named "Avengers: Infinity Quest" - of course I went to google to see that could be found and lo and behold a few covers popped up all from Marvel.com.
I made this mistake once and marked the post to be "published" thinking I could mark it to be put here and there on the site later, but google instantly picked up on it (most likely via a tag).
Anyway, here are covers to Amazing Spider-Man #663 & 664; Avengers: Infinity Quest #1, Captain America #619, Invincible Iron Man #505.
Most likely google picked these up because the names are original. If, say you entered, "Hulk #34" you would get older volume results.
