The search function is your friend, use it well. But just this once, here's a direct dev quote for you:
"Is there a Xbox version of the game in development? No. Are they wanting to bring a version of the game to consoles? Yes. However, the decision whether or not there is a console version of WAR really isn't up to Mythic & EA. It depends on Sony and Microsoft. It depends on if they can make the game and have it still be profitable after the financial dealings with the console maker. That will determine if it gets made. They're looking at ways to do it and they've shown that the technology can easily be adapted to consoles. However, that by no means confirms WAR for the Xbox, or any other console."
