I hope it outsells the PS2. The DS too.
It'll prove the gaming industry is expanding every gen, not getting smaller.
if it doesn't outsell the PS2 it won't mean the industry is getting smaller.
Last gen with PS2 + Xbox + GC + DC i think the total sales were around 170-180 million or so
This gen I could see wii being about 100 mil, PS3 doing a solid 60 mil, and 360 hitting 40 mil. If its something like that the industry will have sold 200 million consoles. And thus it has further expanded, even without the PS2 being outsold.
