Probably not. We've stayed during that same time frame in both 2009 and in 2011 and decorations were not up until after we had departed. MK should be all decorated for the start of the MVMCP's and the other parks will have their decorations going up. It's rather fun to go to a park early in your stay and then when you go back it's all Christmas!
I agree with Kathy about VWL. I suspect that VWL's decorations will probably start going up later in the week after you depart.
The first MVMCP is 11/9, so the MK will be decorated for Christmas by that date with a few exceptions. The garland over Main Street and the Christmas Tree in Town Square will not be installed until after taping of the Disney Parks Christmas Day Parade is done.
