It seems the rumours and hype about the new RACE360, is not true after all. SimBin posted an official statement on their site today.

“We are issuing this statement to counter false rumours currently circulating on the internet regarding a new X360 game.
We do have plans for an upcoming X360 game and an official announcement from Simbin will follow shortly with correct information on title and publisher.
To clarify on a specific point, THQ is not the publisher of our upcoming X360 game.
The information currently circulating is incorrect, said Magnus Ling, Vice President, Simbin Studios.”
