re: Vita, the poster with the picture of iPhone and the other commenting on media player capabilties is spot one.
USA is where iPhone took off, and triggered a sea change in consumer electronics. people are spending more money on these fancy phones that can do most things a portable console could do, and more. movies were a big push with PSP, but that is defunct with smartphones/tablets, and smartphone/tablet gaming has taken off in a huge way. even if that isn't directly comparable to dedicated consoles, that is consumer money going outside the dedicated console ecosystem to fulfill entertainment/gaming. there's only so much free time, and if you found a new use for it, then you don't have time for the other stuff. same goes for other things people stare at their smartphones for: facebook, etc, etc. Vita especially is impacted because it is the more expensive handhold console, so it's purchase is more directly in opposition to somebody buying a new fancy smartphone.
Japan/360, MS just never had it together, I've seen how they didn't get developer relations with Japanese industry, and they just didn't push the right buttons. Chauvinism played/plays a part, but 360 just never challenged the PS3 for the role of 'hardcore game console' that Japanese have in mind for that sector. With Wii's mega success on the other side, there was no reason for Japanese to consider 360. The few exclusives that were bought probably seemed like desperate attempts that didn't change the overall picture.
