Am I reading correctly that there is not yet an easy way to do single-cable 4k/60FPS into a home theater environment? I have pre-ordered one of the new Sony 4K XBR sets and was hoping to have a solution set up by whenever it arrives in June, but I don't think DP is an option since I don't think either the AVR or TV would have it. Currently I have a laptop connected to the existing TV via HDMI...it sounds a little silly on its face that even a beefy desktop won't work for the new TV. Is there such a thing as a DP 1.2 to HDMI 2.0 adapter, and if so, would it carry audio properly?
