Namco Bandai updated the teaser site for the mysterious Capcom/Namco/Sega 3DS project
with ... well, some more teasing. Each "petri dish" now has three x-shaped chromosome-like objects that appear to be color-coded to recall certain characters from that company's stable. We see what appears to be Kite from .hack on the Namco side (the orange, grey, and blue one) and possibly Klonoa (the blue and yellow one); a possible Zero on the Capcom side, and what might be Bayonetta in the Sega dish.
As for what all this means ... without more information on the game itself, it's difficult to determine anything about the potential presence of these crossover characters.
