Do you think there's a possibility that the 2012 Iowa Caucuses will actually be held in December 2011? The reason I ask is there was a lot of debate when the date of Iowa 2008 was being decided.
Only if some other state ends up being even more aggressive than Michigan was in 2008 in terms of early scheduling, thereby pushing IA and NH even earlier. That's less likely to happen this time, as the Dems (presumably) won't have a contested nomination race in 2012, so they have little incentive to engage in even more frontloading. So only states with total GOP control of both the legislature and the governor's office are likely to do something like that this time, and there are only so many such states out there.
