PS3 announced a while ago that they were suffering from a chip shortage, and that they would be short on PS3s when the product finally launched. What a coincidence that this happen with every console that Sony releases.
I feel that I can predict the future, as, before I even knew the name of the PS3, (By the way, what an awesome name.) I was predicting that they would have a "chip shortage".
They know how the market works, and they are shameless about exploiting it.
Doesn't really affect me though, as I intend to get a Wii, and maybe a 360 around then so as to play Halo 3.
