According to this
forum post quoting a British magazine,
Command & Conquer: Red Alert 3, the RTS game in the works at
EA Los Angeles for the PC, Xbox 360 and PS3, will hit the store shelves on October 31st (thanks:
CNC Generals World). Red Alert 3 promises to break new ground in the RTS genre by featuring a fully co-operative campaign while bringing back the series' light-hearted style and classic, action-oriented gameplay.
