Edit: first post
Week ending 30th March 2008:
PlayStation 3 - 12,053
PSP - 133,984
Overall for 1Q (2008 JP only)
PS3: 352,166
PSP: 1,113,853
Difference between this year and last year (1Q 2008 JP ONLY):
PS3: - 13,233
PSP: + 421,601
Let's wait to see what will bring to us next quarter.
My prediction:
PS3: sales will start increasing when Sony release a Slim version with solid price cut.
PSP: sales will reach +20m in Japan alone in this rate.
