As 10k for a 65" tv is a bit more that I would like to pay right now
If you're thinking of getting a 2015 premium 4k TV, 10k is a little exaggerated. I paid $5k for my one-step-down from premium 65" Samsung JS9000, and it's come down $1.5k since I got mine. $3.5k is still an awful lot for a TV, to my mind, but it's much less than $10k. Think of all I saved! And it's a really nice TV.
Spring of 2016 might be a good time to buy. The UHD blu-ray players will be out by then, and there should be a few HDR 4k blu-rays available. I don't think net streaming is likely to give good quality video.
