See, you just pointed out exactly one of the reasons I think it's probably DVC.
They have NO REASON not to announce a CR Suites addition to the CR resort. That would not, obviously, effect their business in any way.
They have EVERY reason not to announce a DVC expansion at the CR resort. They don't want people to wait to buy DVC, undercutting SSR and AKV sales. With 2 years of work left...why give people (I mean "average everyday people..not Dis'ers) a reason to wait for the MK resort?
