Coincidentally it's the country they're getting their ass kicked in
I think that’s strong wording, considering the state of gaming there. It goes without saying that a device that has all the console features a casual gamer could want, but portable, would sell much better in a market that has been heavily driven by mobile gaming for the last decade, than a dedicated home console. It doesn’t make much sense to compare the two, as they really aren’t competing seeing as they’re aimed at different demographics and all. I still say PS4 is doing great, and if it can outsell PS3 in Japan, then it’ll still be a pretty big success, regardless of how many more units Switch sells.
