Well, that tears it, Ubisoft. If you can't even bother to fix your previous games before you go on ahead and type up about new ones, we can't be friends anymore.

Ubisoft has announced another AC game to be coming anytime between April 1st to sometime next year. Ubisoft CEO Yves Guillemot talked a lot about how the game will be totally new and fresh, although considering that's what they said about AC3, and they lied about the PC version and many features ingame, I don't think it's right to trust a Ubisoft employee. Ubisoft stated that sales of AC3 were around the $12 million mark. Quite frankly, I believe they're lying, but nonetheless that's what has been reported.

In December of last year, one employee mentioned the next game could be set in Brazil, and he was never confirmed or denied.
