Audyssey in a player would be problematic - the chips that you need to use to run a player aren't built to run room correction, so you need to build in a separate chip (borrowed from surround receivers/processors) just to run that function.
A year or two ago, you poo-hoo'ed my suggestion that Oppo include HDMI and digital inputs on the BDP-95 so that other forms of input could benefit from the video processor and high quality dac's built into the BDP-95. I think Hank was correct and that in some future release, including room correction would make a lot of sense. Personally, I could see Oppo adding additional digtal inputs as the next iteration, however.
