The total in 13/12 dec WiiU number is not "minus"

Thanks, fixed now.

Have also updated to add numbers for 19 and 26 Dec. PS4 and Wii are now positive for the holiday perios compared to 2014 with one week to go. Xb one has 279K to go to get into positive territory, which is by no means guaranteed. If Xb one is relatively flat YoY for the final week of the holiday period then it will be down YoY by about 80K. But I think that week last year was when Xb one went back up to $399 for the final few days of the week, which would have means a much bigger drop off thean normal. So Xb one probably should be substantially up for the final week and can end up ahead of last year.

Well that's it, aside from future VGC adjustments, which I won't be monitoring, The holiday 2016 numbers are in, and as expected I suppose on a global scale there really was no show down. Here's the final tally so you don;t have to go to the OP to see it.

2014 PS4 6,643,389
2015 PS4 8,868,274 Diff 2,224,885

2014 XOne 4,930,679
2015 XOne 4,840,595 Diff -90,084

2014 WiiU 1,859,682
2015 WiiU 2,101,779 Diff 242,097

Probably not what Microsoft wanted from the best lineup in Xbox history. At least they have next year's best lineup in Xbox history so there is light at the end of the tunnel.

On the other hand, Playstation admitting to having a down year, so they're probably feeling pretty good going into a stacked year.

Splatoon was the best thing that happened to Nintendo regarding the Wii U. If it hadn't been greenlit, they'd probably be looking at a much worse year and a lot more unsatisfied customers.
