I find these assumptions "strange" and it reeks of bias to assume that PC/casuals would automagically prefer the 99$ weak hardware box with some Nintendo games on it!
Well, the Ouya never sold like the Wii (even the year it released) it has a couple of interesting indies and it always online (not a check every 24 hours, if you disconnect the ethernet cable or loose your wi-fi connection for a split second you'll be booted out of any purchased content you may have been using!
So obviously, every market segment would be more excited about a PS4 like machine with the Nintendo titles (maybe some gimmick like the amiboos... I have NO clue why some people buy them).
Anyway, just putting the "sony fans" is a bit wide and disenginious, the PS4 has almost 50% market share, if you were to add some Nintendo fans to the mix it would add to quite a lot of people... and let me tell you, PC gamers in general, like most people who buy gaming hardware favor the better bardware, chances are that if they had to have a console most of them would, like most people lately, buy PS4s or PS4tendos...
Anyway, that's a lot of text for very little.
