I do not think we will have a month long period of no shipments in NA like we did last year. I think at most they diverted 50% of January's stock. which means they would still have 1.2 million to sell duing that month WW. Then after that they begin the holiday stockpiling and stockpiling for big releases.
If production is 2.4 million than I see no more that 1.7 or 8 million sold in Anymonth. Last January production was still at 1.8 million, and they airlifted most of their January Supply. Febuary was slower due to SSBB, MKWII, and WiiFit additional stockpiling (on top of the usual holiday stash buildup).
End of 2009 Predictions (Set, January 1st 2009)
Wii- 72 million 3rd Year Peak, better slate of releases
360- 37 million Should trend down slightly after 3rd year peak
PS3- 29 million Sales should pick up next year, 3rd year peak and price cut
