A quick flick through our Official Age of Apocalypse Calendar reveals that June 29th falls on a Monday, and since neither Xbox Live Monday nor PSN Monday exist, one may speculate that the game may be due sometime during the week of the 29th. We've asked Capcom for further information, though suspect that we'll receive little more than a 768-hit combo of non-commentary.
Update: Says Capcom's Seth Killian: "That's the first time I've heard that date, and so far as I know, it's not correct." It's Marvel vs. Capcom ... on release dates!
