A lot of us skip several upgrade opportunities and just keep saving for something decent that works well with our OS.

Heck, I went over ten years on my last CPU and mobo because I was waiting for the predicted amdgpu nirvana that we have now.

My TV is no different. I've had the same, dumb, 1080p IPS since 2012. Just waiting for a tv that's worth it.

So yeah, if the ideal tv launches at 3k, I'll buy it without a doubt.
I have that money saved from when I didn't leap to 3d, when I didn't leap to OLED and when I didn't leap to 4k.
