I think everyone can agree its not really demand anymore, at least where I live (in Ontario, Canada) ps3's are sitting on the shelfs, and wii's are still very difficult to find. Not that I care really its plain and simple why wii's are selling more, its less than half the price of the ps3. I would love to own a ps3 but its just too expensive right now with the library of games not really appealing to me. I was a huge ps1 and ps2 fan (still play it regularly, guitar hero 2 is a great game ), but withholding buying a ps3.
Maybe when there more software support I will be tempted to purchase one, but ill wait a year and see. Im pretty confident sony will pick it up and gain the same support they had for the past two systems, and I hope so because they gave me countless hours of enjoyment.
