Assassin's Creed Revelations Announced

Ubisoft announces Assassin's Creed Revelations, saying the fourth installment in the stealth/action series will represent the "final chapter in the Ezio trilogy" when it is released this November for Windows, Xbox 360, and PlayStation 3. They offer a logo and a piece of artwork from the game, and say to expect more revelations at E3. In the meantime, here's a chunk of the announcement:
In Assassin’s Creed Revelations, master assassin Ezio Auditore walks in the footsteps of his legendary mentor, Altaïr, on a journey of discovery and revelation. It is a perilous path – one that will take Ezio to Constantinople, the heart of the Ottoman Empire, where a growing army of Templars threatens to destabilize the region.

In addition to Ezio’s award-winning story, the acclaimed online multiplayer experience returns, refined and expanded, with more modes, more maps and more characters that allow players to test their assassin skills against others from around the world. The latest chapter in the Assassin’s Creed saga also includes revolutionary gameplay, allowing players to manipulate the construct of Desmond’s memories and the Animus to decipher the mysteries of his past and gain insight into the future.
