According to a Ubi staffer's CV, the next Assassin's Creed is set for a release this year. As in 2010.
Michael Donnell, a 3D animator at Ubisoft Montreal who is also working on Splinter Cell: Conviction for PS3 according to said CV, has the release date down on his LinkedIn profile.
Previously, the new title was only given a release within Ubisoft's fiscal 2011 calendar, although nothing else was confirmed on its release.
All that is known on the game so far - other than the date - is that it'll star Ezio from Assassin's Creed II, will be a continuation from said title and will have multiplayer.
As for Splinter Cell: Conviction PS3, that is not the first time that has appeared on someone's CV. Only last week, it appeared on another LinkedIn CV, which showed the platform together with the game.
In the meantime, Conviction is set to release next week for 360, with a PC release on April 29.
