as Cyber previously pointed out, the PC version is going to be delayed for ACII, this in fact isn't true.
First: If you live in Canada you can expect ACII to be released November 17th 2009
Second: If you live anywhere else in NA you can expect it November 18th 2009 (or sometime close to it but not before it)
It's only being delayed in EU and personally i think it should, i mean they get the good special edition so they should wait for it, in NA there is no special editon for PC even tho the game is made in Montreal, Canada!
So i just wanted to clear that up for everyone. :D
