Not saying PS consoles combined is selling more than Nintendo but it is going up in sales as other produces will be going down. When the Wii starts to slow down to about 15-20k, it wont be cause no one wants one, it would be cause everyone has one. But when we look at PS2 compared to GC, yea we can SO do that, we see the PS2 is selling like it was new. It also further proves that Sony made the PS2 damn near perfect. I wouldnt be surprised if in 2010 the PS2 is still pushing units in the double digits and Nintendo's Wii is selling 100 a week.
I expect the Wii sales to fall drasticly. After Mario, Brawl and Metroid, what else is there? Sounds a lot like the GC line up with, Mario, Melee, and Metroid.
