New Assassin's Creed installment, Brotherhood, finally introduced at E3! You can take a peek at some screenshots uploaded to AC official website (the same size & quality is here on Moddb ;-)).
Below 2 HD trailers.
Also, Gabe Graziani invites you to the E3 Q&A (questions and answers) in this very YouTube video:
Assassin's Creed Brotherhood E3 Q&A Invite
You just need to post a question and hope yours will be chosen to be answered! Best luck!
And unfortunately, among the good news is a bad news - a very nasty one, to be sincere. As some newsposts give away (from the official statement at E3), the beta of ACB will be only for PS3 owners! = /
