My LG BH100 dealer claims they are moving BH100s as fast as they bring them in. As long as this is the case, no reason for LG or even their competitors to drop the price of Dual format players very much. And maybe it IS expensive to build a dual format player.
I don't know about HDMI, but 5.1 uncompressed PCM and TrueHD via the analog 5.1 outputs sounds pretty good. And I'm getting very good results with the DTS core track via Coax digital output. Can't say I'm real impressed with DDplus but that might be a player issue.
BLU RAY - 53+PE (if your quantity is zero, you are missing out on too many movies)
HD DVD - 10 (if your quantity is zero, you are still missing out).
