Ubisoft will bring Watch Dogs and Assassin's Creed 4 to the newly announced Xbox One later this year. Until now both games had only been confirmed for current-gen platforms, PC, and PS4.

Further to these two, the French publisher will bring at least four more games to the Xbox One in the first 12 months it's on the market.

"The next generation of consoles will reinvigorate our industry and make it possible for us to deliver incredible new entertainment to gamers," said Yves Guillemot, co-founder and chief executive officer, Ubisoft. "Our teams are using the innovations in connectivity, immersion and social gaming included in Xbox One to create original and memorable next-gen gaming experiences."

Microsoft revealed earlier tonight that the Xbox One will release worldwide later this year, but didn't reveal any more concrete details.
