Full the love of god. Microsoft has like 5 different bundles available and 3 of them are Holiday bundles. We are not just talking about 1 Holiday bundle like Sony has. So of course you are going to see a lot more Microsoft consoles on shelves.
250 GB HD, Forza 4, Skyrim, and BO 2
250 GB HD Forza 4 and Skyrim
4 GB HD with Disneyland and Kinect Adventures
4GB HD with Skylanders
Halo 4 Bundle
We also don't know how many each company shipped and we sure as hell can't be using 5 posters local area as a measuring stick for the entire country.
