Nissan Dumping All North American Motorsports Operations?

UPDATE:We have conformation of this rumor, read the whole post on Nissan Racing with quotes from Nissan Motors. We've heard from a little birdie that a new accountant at Nissan has determined that NISMO North America/Nissan Racing North America is too expensive and must end. That means no more Nissan-backed CORR, Grand-Am or Drifting teams. The announcement was apparently made internally a week ago so that teams can find new manufacturers. All before the Nissan GTR hits our shores. Awesome! The rumor is unconfirmed, but also un-denied, so take that for what it's worth.
