I went to a show in October and the sim2 reps said they had no idea when a 1080p C3X was going to released because TI hadn't signed an agreement with anyone. I went to another show in December, asked the same question and they said there would be a 1080p C3X by the end of 2007. CES seems a little early to be showing one but if they do then it will have been the best kept pre-CES secret so far.
As far as improvements go, the HT3000 was quite a jump up in quality from HT300E so I expect we will see a similar jump with the follow up to the C3X. I never got to see the delta engine 3 chip HT500, can anyone give an indication of how much of jump in quality the C3X was from that?
I hope this doesn't turn out to be another LED projector
