Microsoft confirmed their keynote predictions today with the announcement of the Microsoft Game Room, a new service for playing classic arcade games on XBox Live or the Games for Windows network.

The official release confirms our earlier post-conference report detailing Robert Bach's promises of a "retro gaming service" that offers players a chance to play classic arcade games alone or with friends using Xbox Live Avatars and voice chat. Cross-platform play will be available as players take turns competing against each other or alone in ranked games to earn a place on the global leaderboards.

The requisite Xbox Live Achievement system is in place across both platforms and players will be able to message friends with custom invites and challenges, though we have no word yet on whether or not achievements are platform-specific or tied to one global account.
