The original artwork done by Tatsunoko won’t be in the North American version. Capcom commissioned Udon to create all new endings for Tatsunoko vs. Capcom: Ultimate All-Stars.
As announced by Udon on their blog, Tatsunoko vs. Capcom: Ultimate All-Stars will have 26 new story endings. Morrigan’s ending definitely looks different. In the Japanese version, Morrigan’s story ends in a non sequitur way with her playing the game.
I suppose that means Saki’s Quiz Nanairo Dreams parody ending and Ryu’s “appearance” in Lost Planet are out too.
