That's because of Microsoft paying them a truckload of cash.

 At least they are trying to appeal to the japanese audience.

On topic: I think it depends on what kind of games you make, but I would say install base is more important. 

Uhh, yea, I wasn't even talking about that, I was refering to how it has nothing to do with the 360's attach-rate.
