There where only a limited number of PS3's that stores had so there are only a limited number out causing inflation. The next batch (from what I have heard) won't come out for a while which is making the hype even bigger.
I think I would wait in a line for two days to buy something for $600 and make a profit of around 3,500. That is a HELL of a lot of money and i think that it would worth it.
Buy the ticket, take the ride
Too weird to live, to rare to die
You are my one and only Chicagooo
To dream in RED, to dream in WHITE
For you we all shout into the night
