Sheesh.  This isn't a good sign.  Why does Sony always have issues with nVidia.  They had similar problems with the RSX just before the ps3's launch.  They had to downclock it from 550mhz to 500 at the last second due to heat issues.

I hope they get everything ironed out, and I hope this doesn't lead to yet another console that has a launch price that doesn't quite match the machine's capabilites.

no it's still @ 550
