im sure many can, its not really the wiiu beating the x1 its the PS4 smashing the X1 with wiiu getting left over sales that count up to over the X1.

This is part of the reason I've been working on that chart.  I've been wanting to compare them directly against each other and see if there are any long-term trends or patterns from generation to generation.  Easier said than done, though.  This has been one of those projects that starts out with the naive assumption that it will be a quick job, only for the reality of how much work it is to quickly set in.  And before you know it, you're sitting there with your head in your hands, thinking "Why did I want to do this again?"

All of these are reasonable predictions, besides the last two. There's no way PSP can outsell Vita if Vita beat PSP last year, Vita is up YOY, and PSP is down YOY.

With this awful Vita line up i can expect anything ,Vita outselling PSP will depend on Japan number

The amount Vita is outselling PSP in the US weekly is bound to grow in the holidays. If PSP beats Vita in Japan, the amount won't be enough to cover how much Vita beats PSP in the US.
