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.

Ninja Gaiden - 70k
NG: Sigma - 90k
Dragon Sword - 9k

Although one is a remake, and the another was on the xbox which didn't sell many consoles in Japan.  But going by those numbers, Ninja Gaiden isn't very mainstream in Japan.  Maybe the NES games were, but not now.
