X360 - 7 million: Kinect will be big as with so huge marketing campaign you really can't fail. X360 will post big numbers in USA and UK and should to reasonable well in continental Europe too.
PS3 - 6 million: Sales will fall in USA and Japan compared to last holidays but if GT5 comes this year it should give good boost to sales in Europe. Also Move seems to be reasonable hit in continental Europe so PS3 will ride these holidays with Europe. Sony probably also continues to conquer developing markets so it has edge there compared to MS and Nintendo.
Wii - 8 million: Although Wii is now doing pretty badly compared to other two I still think it will have biggest quarter. Every year Nintendo's platforms see most boost when we come to the holidays so i don't see why that would change. Also when it comes to games that actually use motion controlls wisely and still are deep Wii has huge edge compared to Kinect and Move.
