StingingVelvet: They're not going to cater much to Japan because they don't give a shit about Japan. Hell, they barely give a shit about Europe.
Actually, it's not that they don't give a shit about Japan, it's more Japan doesn't give a shit about them. MS fucked up their introduction to Japan by doing exactly what they were advised not to when releasing the Xbox. The result was pissing off many people in the Japanese gaming industry that they needed in order to establish a presence here.
They never managed to get anywhere with the 360 as a result. They were, in fact, thoroughly humiliated; being consistently out performed by the PS2 - a last generation console. The few unique exclusives they had in Japan ultimately cut their losses and released on the PS3 in order to make a profit. So it's no wonder they canned all advertising and closed down their Japanese gaming division.
Now if they don't release here; that's fine. It'd be for the best. But they really shouldn't be stringing along the few customers they have here. In this region more than any other, they need to give a firm answer as to when, or if, it's going to release. They can't just display an Xbox One section on the JP site and leave it at that. Although I expect they are using that to gauge interest with the "sigh up for newsletter" button. But with no firm comment on release, they're not likely to get much interest at all.
