It is more mainstream in Japan, but a niche game outside Japan. MS will hope this will have some effect on 360 sales there, as small as it is. Its not a system seller in my eyes.

Considering how few people owned Xboxes in Japan, and considering the low sales of NGS on the ps3 in the region, I'd say NG is far from mainstream there.
