I can't back this up with facts or anything and I may be off,but I always looked at the reason the PS2 had such longevity was due to the PS3's huge price tag and such a shorted amount on initial release. I know that I seriously contemplated getting a PS2 and I'm guessing that parents whose kids were demanding a game system for Christmas and didn't have a PS2 were like "Hey...it's waaaaay cheaper,easier to find,games are cheaper too and there's a ton to choose from and it'll make little Billy and Mary happy.....also Uncle Leo who lives in our basement."
Hell,I remember too how crazy it was to find a Wii and I just lucked into walking into Wal-Mart with the intent of getting one but settling for a PS2 if they didn't because that tax return money was being spent one way or the other and there was a Wii there. So my point...if it can be called such is that I could very well say that the possibility of a brief but noticeable spike in Wii sales could come around the holidays and last past that a few months if:
A: The Wii U's price tag is hefty
B:The Wii's price drops to say $129 or $99 even.
Just my nickel.
