Any comparisons at this point are pointless. We can start drawing the first conclusions after the first week of PS4 sales in Europe, this is why:
NA = EU <- they are pretty much equal in terms of market size.
XO will be available 2 weeks in NA and 2 weeks in EU = 4 weeks. I know it's not available everywhere (fuck you MS!), but it is available in the largest markets and 2nd week sales mean more than the third's, so XO being out here for the 2nd week means more than PS4 being out for the 3rd week in NA.
PS4 will be out 3 weeks in NA and 1 week in EU = 4 weeks.
So now we will have both consoles available for 4 weeks in almost the same territory, since XO wouldn't sell like crazy in the countries that they ignored either way. That will be the time to start comparisons. Now both sides are grasping at straws and manipulating facts in their favour. We have to wait 11 more days and it will be undeniably clear who won the launch.
