Actually the first three months of PS3 sales in Japan have been nearly identical in 2008 & 2009
2008: 347,611
2009: 350,601
Less than a 1% increase.
The difference is that in early 2008 Wii had Brawl and Wii Fit to perk up demand, and Wii had a much stronger 2007 holiday so demand/supply was still balancing out. Its a bit different this year (again first three months of each year):
2008: 1,069,039
2009: 412,361
Nearly a sixty percent drop.
Monster Hunter G should debut to at least 50,000 and probably 75,000+ for Wii which (given that it has a demo of Monster Hunter 3) should insure Wii sales for Apr-June are higher (400k+) than they would have been other wise (320k).
I wrote about all this in the article on the front page if your interested in seeing the dips/rises for 2007-2009 visually.
