Well, I think it is wrong of you not to include The Playroom, when technically it is a game/mini-games.

You can decide what is a game and what isn't.

1. The WiiU is a stop gap console set between 2 generations. If someone is looking for a next gen console, they aren't looking at a WiiU. To put it in another way, if I go into a Best Buy and want to buy a BR player. If a cheap price is enticing to me, I am not going to walk out with a $40 DVD player instead of an $80 Bluray player. If someone is looking for a next gen console they can buy the PS4 for $400 or the Xbone for $500. If you're throwing in the WiiU you might as well throw in the 3DS, Vita and even Ouya. They are equally relevant.

2. See #1 regarding price. Both consoles are available in the US, one is $100 cheaper. That can explain the disparity there. Of course, I don't see why I'd need to explain any disparity. I never said that all things equal the Xbox One would sell more. These are just the 2 most glaring reasons why the PS4 it outselling it. You can throw in world wide brand advantage, more powerful, and I would also throw in confusion from consumers after MS's initial reveal. I still know many people who wonder if the Xbone can play used games or requires constant Internets.

truth is i created the list buy going to the xbox marketplace and sony online entertainment store.  i missed playroom because it pre-loaded onto ps4's not a "purchase".   my bad i suppose.  i won't be updating the OP though.  sorry.

It definitly has the brightest future. Its pretty much confirmed that it will be the dominant system this cycle.
