Regardless of which is the best seller in what country, retailer, on Black Friday, on launch day etc, the fact is, as of now the PS4 is pushing ahead of the XBone by a large gap of around 700K worldwide.

That's all that matters, the actual units sold, till today.

By March 2014, I would predict PS4 to be around 6 to 7 miliion minimum (with a large contribution from Japan where it launches in Feb) whereas the XBone will be up to 3million at most. As more and more normal people (i.e. those that don't frequent gaming sites like us) are aware of the performance diference between the 2, the gap will be much bigger moving forward.

In terms of games, there will likely be many new ones appearing for the upcoming Japan launch.
