Ps4 not following this logic this January in Japan.
PS4 sales this January will be exception because it getting one of biggest Japanese IPs in January.
I know that, just pointing out it isn't fact what he's saying. It's not so black and white.
And if switch had stock in January in Japan its numbers would be huge.
Fact is that in almost all cases December is stronger than January, few exceptions are possible but that really dont change hole picture.
Offcourse that numbers would be bigger without stock problems, but that goes also for December, so December would be stronger than January in any case for Switch, and I actually wrote that sales in January can be good for January sales or despite its January.
