I would say that I extremely doubt it. Although I can't rule it out completely. A lot of it depends on what other the console manufacturers do. Do they drop their price and when? Do they release a future console and when? If nobody releases a new console for at least the next seven or eight years. all the systems will be priced very low. We could look at a market where the Wii is less than $100 and the 360's top model could very well be under $150 and even the same for PS3 possibly.
If that was the case, anyone slightly interested in gaming couldn't pass on owning a second or even all three of the systems. And if it did get to that price, a lot of casuals would likely buy one too. So while I doubt it would happen, who knows what the future holds? So much of it depends on the competition and what they decide to do.
I'll come up with something better eventually...
