Some sloppy web design may have revealed the final four characters for the North American version of Capcom's Tatsunoko VS. Capcom, and one of them has covered wars, ya know?

These characters would appear to be Mega Man Zero, Dead Rising's Frank West, Yatterman #2 and Joe Asakura, aka Jason from Battle of the Planets.
Along with Tekkaman Blade, who was recently revealed, those characters would seem to round out the North American Tatsunoko VS. Capcom roster quite nicely.
Of course sloppy website coding is by no means official confirmation. We've contacted Capcom about this rumour, and quickly received a "No comment!" Make of that what you will.
