I've attempted to estimate Canadian GTA IV breakdown by comparing US attach rate for US January LTD numbers to Canadian attach rate for Canadian January LTD. I compared it to January as this is the latest LTD I have for Canada, and it's best to compare like to like. Canada had a slightly higher overal attach rate to January LTD, at 25% compared to 23% for the US. Taking that in to account I then applied the difference in attach rate for 360 Vs PS3 in US to Canada. It came up with a ratio of 1.5:1 for Canada. It's lower than the US due to 360 Vs PS3 market share being a little closer than in the US.
Anyway, my estimates for GTA IV in Canada:
360: 162k
PS3: 108k
Mario Kart should be somewhere between those. Going by US figures GT5:P & SSBB should be quite a bit lower, somewhere around the 25k-30k range.
Hopefully we might get the actual breakdown from NPD somewhere.
Edit: I forgot GTA IV Special Edition is a separate SKU in this chart, so the band for Mario Kart will be slightly lower.
