Now, when I look like the workload on the individual consoles since we say about early 2012 auschaut:
Wii - games we no longer (actually was the console in this period only I believe 1x eingeschatet)
PS3 - about 10% (in direct comparison between PS3 and XBox360)
XBox360 - about 90%
The shows I think so much has the XBox360 clearly prevailed with us as number 1. There are a lot of reasons of hardware (especially the controler) via software up to Xbox Live. I do not want to list all the points in detail but I am, as mentioned earlier, convinced that only someone of a sufficient time on both platforms (Wii, I let conscious way) has played this may be compared. Even if I leave now incorporated the factors taste and habit I can really imagine very difficult as a PS3 umterm stroke can actually liked it better than the XBox. But about taste can be known not argue.
As for me for the future (next Genaration) in the XBox is a bit worried the move towards this Kinect. I think if that too much going in the direction I'm going more towards Sony change.
I think that the next generation (Xbox720? And PS4) will anyway be more similar.
Currently we have about 10-15 Top tracks on the current XBox and in any case the two titles 'The Last of Us' and 'Beyond: Two Souls' play on the PS3!
