Yeah I'm sure Sony can also manage to do a global launch with one console for each major territory and then fuck all inventory for the next 3 months... Just like ms did
But at the same time in all regions? I think it's pretty obvious neither will want to let the other get a jump on them but has Sony ever done a global console release? MS did it on the 360 if I remember right.
Both next gen consoles to release in November.
If it ends up as both launch in November but we don't get one of them until Q1 of the following year in Europe that will be a blunder I think. Unless of course they both do that.
