ioi i can guess why - 360 hardware was driven by guitar hero at the end..if guitar hero sales from your sources are off, then the hardware will be off for 360 as well. Personally, I had expected 50k for 360/week until i saw your weekly data estimates. As for Wii, I don't think Gamestop would just call out Nintendo unless they had good information that shipments were tiny at the end of March. However, if your sources had wii in stock more so than other places..then the extrapolation messed the information up. In terms of raw data you are fairly close for PS3..but % wise..I think only DS was within 20%. DS sells everywhere, so it will likely have the least inaccuracy going forward. If data stays similar to this, I would trust most of the software, and make the totals on here 2/3 of the extrapolation.
