As for what I think...
hard to say. Unless you really Need Final Fantasy and Metal Gear Solid (which I assume you don't since you have to ask thing question.)
I'd go with 360.
PS3 has some really good Japanese games announced, but a lot of them arent' likely to leave Japan.
While 360 has shown a willingness to buy japanese focused exclusives and timed exlusives which basically have to come out in the US as well since they aren't going to be big hits in Japan with no one having a 360.
Too many people have bought PS3's expecting their favorites franchises and that a rush of japanese support would hit PS3 and have been disapointed.
If you had to get one today. 360 would oddly be the "Safe" choice... and the one more likely to get more exclusive Japanese games released in the US based on current trends.
