Just wondering what all it entails. I think I understand that the original Sil503 progressive chip stays in and does not get replaced by the newer Sil504 chip. I think John Dawson said that they shrunk the die on the newer chip therefore it operates at a lower temp. but otherwise no significant performance differences for progressive scan. Does the mpeg board get replaced to the newest Vaddis chip? And if yes, I assume it still has the chroma bug anamolies. Any other key improvements included? My player is in for the upgrade though I don't know when it will be done.
