Namco, SEGA and Capcom are prepping the now infamous mystery reveal site for the Nintendo 3DS collaboration the firms are working on.

Meanwhile, AGB has posted a graphic which may or may not depict the characters from each developer which are to appear in the game. It’s an interesting theory, but we’ll just have to wait until a formal announcement to know for sure.
