New title to feature Ezio. Not an expansion for Assassin's Creed II.
"The 2010-11 fiscal year will see a greater number of franchise releases than fiscal year 2009-10, including Tom Clancy's Splinter Cell Conviction, a new game in the Tom Clancy's Ghost Recon series, Prince of Persia The Forgotten Sands, Driver, Raving Rabbids 4 and a new episode of Assassin's Creed, which will be the first in the series to have an online multiplayer mode," the statement reads.
The update did not provide additional details on this new Assassin's Creed episode, such as a release date or if this mode is part of the two expansion downloads Ubisoft plans to roll out in early 2010 for Assassin's Creed 2.
IGN has contacted Ubisoft for clarification and will update this story when we hear back.
Update: Ubisoft has clarified, saying this is a new title featuring Ezio, and is not an expansion for Assassin's Creed 2. The new online multiplayer mode will be for an entirely new Assassin's Creed product. The Assassin's Creed Episodes project will pick up where Assassin's Creed 2 left off.
