The Wii U and PS4 (even with limited information) are both a hard sell. Switching to either system would mean that I would not be able to play with my current friends (unless they all switched which is unlikely), my achievements would be set back to basically zero (or none at all in Nintendo's case which is a major strike against that system), and all the games/DLC I currently have would not transfer which would further add to the already high costs of buying a new system and the other things that come along with it.
This gen, more than any other, has made the prospect of jumping from one console to another rather unreasonable. When I switched from PS3 to Xbox back in 2008, there was virtually no DLC or other content that I had purchased that had to be rebought on a new system ... and most of my friends did not have a HD console at the time either. Now, I have just too much that I would lose if I switched.
Along with this, I am of the rare opinion that the Xbox and the PS3 are incredibly similiar, and they are much more alike then they are different. I see them as nearly identical systems, and neither has an extreme edge over the other ... just a few minor advantages to each. Considering the fact that I find that the best games are third party, exclusive games from Microsoft and Sony really mean nothing to me so really the only thing keeping me with Xbox is the wealth of content I have already purchased for it along with a bunch of friends that play the system with me (achievements and cross game voice chat are factors as well).
The only change that could make me switch would be either a fantastic new feature (not sure what, but it would have to be astounding ... and a touch screen controller is certainly not in this category), or a colossal mistake on the part of Xbox (like removing used games or not allowing content to transfer from Xbox 360 to the Nextbox).
