I guess Tatsunoko vs Capcom is already leaked on the net according to wii.qj.net
it looks like we might get some more characters in this game, maybe from DLC perhaps. all is according to wii.nintendolife.
Impatience seems to be a common characteristic of gamers. Yet another game joins in on the "Leaked on Torrent" list, and it's the all-star fighting Tatsunoko vs Capcom. A Twitter post made in the news4pirates page confirm that the game has indeed been leaked onto the Internet. Are you getting the game's real copy or are you going for the leaked version?
Convincing though it appears, we must point out that this is not official game art
The Ace Attorney and other characters may arrive as DLC
Capcom fans disappointed at Phoenix Wright's exclusion from upcoming brawler Tatsunoko Vs. Capcom: Ultimate All Stars may have reason to get their hopes up again, as Destructoid reports that producer Ryota Niitsuma claimed if Nintendo would allow it then extra characters may be added to the game as downloadable content.
The much-hyped fighter has gamers excited, and the promise of extra content to boost the game's longevity can only be a good thing, especially if it means laying the smack down with gaming's greatest defense attorney. From the sound of things, if Nintendo give the green light this could well be a possibility, so here's hoping the Big N pull their finger out and give Capcom some freedom to expand the game as they see fit. After all, keeping third-party developers sweet is vital to the Wii's future success – even more so than maintaining a "hardcore" fanbase.
Plus, shouting "Objection!" into Mega Man's face will likely never get old.
