1.1 million units, in one extra week, without Japan, is a pretty big deal.
Contrary to what people here keep saying, both systems are about equally limited by supply issues, so it's hard to sell. The PS4 and Xbox One are about equally easy/difficult to find.
But 1.1 million without your home turf is a very strong start. Not sure how people argue otherwise. Is it meaningful long-term? No, look at the Wii. Things will fluctuate often and rapidly. But it's a really strong start out the gate.
