Capcom more formally announced Tatsunoko vs. Capcom: Ultimate All Stars. The crossover Wii fighting game is scheduled to come out in North America this winter with features not found in the Japanese version.
Worldwide online play over Nintendo Wi-Fi is a key addition. Players can choose four modes: friend, rival, free, and ranked battles. When you fight online a title is shown for the world to see. Titles can be customized by earning points.
Five new characters will join the spectacle in the North American version bringing the total roster to 26. The Japanese version had 22 characters, not including the boss. The downside is one character from the Tatsunoko side was lost due to licensing issues.
I played the US version today and can confirm all of the Tatsunoko characters except Hakushon Daimaou (the genie) were playable.
