BV10 is rumoured to be a very thin TV: No place for a player.
If Sony could get a drive in to their PS3 in 2007, I'm sure B&O can get a slimline Blu-ray player in to a BV10 by late 2009. Even if it's 2" deep, it should be possible.
Mind you, I don't see the value of a player in a slimline wall-mounted TV. How would a kid or someone get the disc in and out the TV?
