If the PS3 does as well as Sony hopes it will, it will dramatically reduce the proce of Blu-Ray players - everyone with a PS3 will have one anyway. And it will pave the way for a new technology.

PS1 had CD.
PS2 had DVD.
PS3 has BR.

And for their next gen console they're supposed to go with the same graphics they've already got, and the same processor the PS2 has got? Yeah, that's gonna sell well.
