The upcoming release will feature new characters and hopefully online play.
Tatsunoko vs. Capcom: Ultimate All Stars, the North American version of last year's Japanese game Tatsunoko vs. Capcom: Cross Generation of Heroes, will feature some additions and be more like a "championship edition," according to Capcom's Senior Community Manager Seth Killian.
He stated that the North American version will feature additional characters and if all goes well, online play. There is no word on who the additional characters will be, but there will be an even amount added to each side.
Tatsunoko vs. Capcom: Ultimate All Stars is coming out later this year or early next year for Wii.
