I've been observing the Wii lately and thought to myself the odds of the Wii hiting 100 million are looking more and more bleak everyday. It's obvious to all now that the Wii is done and it's sales will continue to diminish. Not to mention with the release of the Wii U sometime in the second half of 2012 which will really slash it's sales. The DS was selling great until the 3DS came along now it's lucky to be over 50K a week, I see an even worst similarity with the Wii.
I think sales will keep continue to drop up until it's almost immossible to hit 100 million. Nintendo is done with the Wii and are now focusing everything on the Wii U's release. I mean whats left for the wii for system sellers?
Anyway things are looking very bleak to hit that 100 million barrier, if it does pass this milestone it'll barely get over. Won't beat the PSONE.
