I think that it differentiates how strange the J-market is for the 360. Gears of War has only sold *maybe* 5% of the total software upto this point, and has maybe a 30% attach ratio per system. Blue Dragon, on the other hand, has about 15% of the total 360 games sold in Japan, and a near-50% attach ratio. Certainly it's interesting, as it's kinda like the Nintendo Wii: your never gonna know what kind of attatch ratios your gonna get.
Back from the dead, I'm afraid.
