Xbox 360: 40 M
Ps3: 30 M
I think that MS will low the xbox 360 price aroud U$ 50 again and I think that a new xbox model will come, not slim, but smaller - CPU + GPU integration (mabe on october-november).
I think that the Ps3 price cut will be around U$ 50 and not U$ 100.
I don't think that the the Blu Ray is the only component that makes Ps3 expensive
Don't forget:
Ps3= Cell + Blu Ray + Wi-Fi + bluetooth + Memory Cards reader + PsN cost of mantaining
