So WiiU sales are at 7.45m with about 150k pending for Smash week (80k~ US, 70k elsewhere) taking it to 7.6m
Then we have Black Friday the following week, which could see about 200k in the US, along with Japan and Europe launch of Smash which should easily add another 200k. Sales should at the least be above 8m as we enter December.
This leaves on average about 400k a week in December (maybe 350k if it does really well on Black Friday week).
7th Dec - 186k
14th Dec - 265k
21st Dec - 342k
28th Dec - 232k
4th Jan - 117k
Total - 1.142m
