There are several ways they could go on this but hopefully it's similar to what Bioshock did with its collection.
Ezio will contain all the single player DLC which amounts to 250gs for The Da Vinci Disappearance in Brotherhood and the often loathed 250gs for The Lost Archive in Revelations.
Brotherhood and Revelations had multiplayer achievements in the base game which will be gone.
So hopefully it will show as 3 separate games worth about 1K each.
God help me if they stuff it all into 1K.
Any other guesses?
The collection releases Nov. 15th. Does @Freamwhole what to make December (or Nov.) AC month?
