Yeah... Maybe if X1 released in November of this year it would make a very slight difference in sales for its lifetime, but unless MS pours a lot of resources into the Japan market its going to be a farts chance that it does considerably better than the X360 did. IF the features of X1, and undiscovered interesting Cloud Tech become a big draw for X1 world wide it would likely still only have a minor impact in Japan.
PS4 for the time being will be the go to high end console. If Samsung or Apple come out with a viable hard core gaming platform then that changes things, but Sony will outsell MS in Japan by a decent to wide margin even if X1 is killing world wide. X1 needs some heavy hitter exclusive titles/exclusive tech features to even make much of a dent. Thats just the reality it faces with what we know about the Japan brand/gaming preferences.
