Its looking more and more like the 360 will give the PS3 a run for its money. The 360 is already tracking well above the best year in Japan in MS history (if it didn't sell a single unit for the next 4 weeks, it'd still be tracking above the best year for any box)....Not only that, it tracked about 250% above WOW sales.
The big question is how well the 360 will do in J-pan when Biohazard 5, DMC4, or other major PS2 titles are on 360 as a multi-port.
At any rate, Sony is securing themselves a very poor 30% marketshare in Japan, 35% if they are lucky.
*cough* you mean PS3. ;)
and *cough* 360 wont be seeing DMC4. ;)
