The presentation of the PS3 is generally considered a disappointment:
499 for the 20 gig version (rumoured to be without other substantial options like HDMI-support)
599 for the 60 gig version.
The boomerang has been replaced by the classic ps2 controller but with a tilt sensor and a guide button. R2 and L2 have become triggers.
They showed some playable demo's which were quite pretty but after that it was trailers. People generally expected more and haven't dropped any jaws or blew any minds..
