Assassin's Creed II hit just two weeks ago, received well both critically and commercially.  As with most new games, the question regarding incoming DLC was more of a 'when' than an 'if'.  Very predictably, UbiSoft has just announced the first batch of Assassin's Creed II DLC. 

UbiSoft was pretty vague in regards to the specifics of these DLC episodes, but the player will once again be taking up the mantle of Ezio.  So far, there are 2 batches of DLC planned.  The first release, Battle of Forli, is set for January, and the second release, Bonfire of the Vanities, is slated for February.  Both DLC packs weigh in at 1GB.
