Japan - The seismic effects of market shifts and economic gloom in combination with a rather short release list have made a significant impact for Square Enix. In 2007, twenty-two releases spread across five systems (DS, PSP, PS2, Wii, 360) added up to a shockingly huge 6.4 million units sold.
In contrast, Square Enix's 2008 effort of ten releases across four systems (DS, PSP, Wii, 360) resulted in a far lesser 1.7 million units sold.* This is a 4.5 million unit difference and is a eye-popping 73.81% decline from 2007.
