Those asking about high/low weeks... obviously week 5 will see a big boost due to Black Friday.... the final 3 weeks should be roughly similar to last year given there is only 1 day difference.... which means week 8 should see the largest sales for each console, however the step back by a day should see week 9 closer to week 8 than last year.
All this is my opinion of course.... another point to this thread is to discuss things like this, so if you have a different opinion then voice it.
Personally I think everyone is underestimating the Wii quite a bit... particularly now that week -1 results are in (week -1 being the week before week 0, which is before week 1 ) and it has increased over the previous week.
