Project Legacy?
Does anybody know when the last three chapters of the "holidays" memory set in project Legacy will appear? When you mouse over the icons of those chapters now it still says "coming 2011!" so I doubt they will ever finish it.
(!!!SPOILER ALERT!!! Do not read on if you haven't unlocked the fourth abstergo file in the MP of AC: Revelations!)
Also, in one of the abstergo files in the MP of Assassin's Creed: Revelations it is said that Project legacy has been aborted because of security reasons. This probably refers to the system hacks performed by the notorious and mysterious figure that calls himself Erudito.
It looks to me like they've abandoned it.
And including that message within AC: Revelations makes it part of the story, avoiding the fact that PL probably just wasn't successful enough.
Shame, I quite enjoyed it. There's been a 'Divine Science Story Pack' advertised as 'Coming Soon' for ages too. 
I heard somewhere of someone playing the Divine Science Pack on these forums, although I don't remember who or where I read that.
I enjoyed Project Legacy, sure got tedious; but that was only after completing everything.
A nice expansion to AC:B, even though it was only temporary. Technology is just the same. Just gotta move on...
