Well, since there was next to zero info provided about them at CES, I'll start with a guess! I was told that they both will have HDMI1.3, which seems like a no-brainer. My guess is that they will hopefully use some scaled-down version of the PS3 hardware and the more expensive one will decode all the new audio codecs internally and output them as either a direct stream or as 7.1 LPCM as well as output them via a 7.1 analog output. The less expensive one will probably only stream the new codecs and only have a stereo analog output. Other than these differences, they should be about the same. Just a guess, though. Anyone else like to take a shot at predicting the future?
