Ok this is my first blog post, please comment about it.
Anyways Ive done some snooping around and I managed to salvage this piece of info.
In an interview, Assassins creed Revelations creative director Alexandre Amancio confirmed that AC3 will be about another character, it will still be focusing on Desmonds ancestors but it will be set in a different time period and a different person.
I also managed to scoop out that AC3 may be set in the American Revolution and it also has something to do with the Decleration of Independance.
I will report back if I find anything else.
