Scalpers always are there when a console launches. They are another middle man. They don't factor into the market unless their is not enough demand for the product. The Wii U demand was small enough to not stabilize the market initially. You can speculate that the PS4/Xbox One won't have enough demand to stabilize the scalpers as well, but it's not proof that they can't stabilize. I think the PS3 had a rough start because of it's launch price, but I still remember it being somewhat difficult to obtain during it's first couple of months.
