We're currently trying to follow up with Realtime Worlds and EA for confirmation. We'll update if we hear anything back.
Update 2: Realtime Worlds: "Realtime Worlds have only ever announced a Q1 2010 launch window. Any other dates you may see are either assumptions or speculations based on this."
Update: EA reiterated that "early 2010" is its release window, also "there are currently no plans for a 360 version."
