The PS3 jump appears less because it was still falling from the PES boost
X360 boost wasn't too bad, wasn't it about 8-9k last week?
However, with the exception of DS, gaming is dieing in Japan.
Compared to same week last year:
Wii and PS3 are about 60% of 2007
PS2 is about 30%
PSP about 40%
X360 is the only one to improve, but only slightly and it's still not significant.
DS is managing about 90% of last year.
