Capcom opened a website for the Japanese version of Tatsunoko vs. Capcom Ultimate All-Stars which confirms worldwide online play and leaks the remaining new characters.
Tekkaman Blade is officially confirmed for Ultimate All-Stars. A Shoryuken forum member dug around the site’s source code and discovered broken image links that point to new characters.
From the Tatsunoko side we have:
Yatterman No. 2 from Yatterman (she’s on the left)
Joe Asakura from Gatchaman
And from Capcom’s crew we have:
Frank West from Dead Rising
Zero from Mega Man Zero / Mega Man X
The last clue is an ambiguous file called “oncharactor_btn_zero.jpg”. It could mean Zero in his Mega Man Zero look or classic Zero from Mega Man X. There’s something left Capcom to announce after all!
