I'm so not a purist. I think 3D is going to be where we're headed. Can't stop it. Folks should stop fighting it and get on board. The only thing that needs to go, are the freaking glasses.
I heard Toshiba pulled off a glasses-less 3D TV in Asia, but could only make it work on a 27 inch. That imo, is the future of it. 3D TV, no glasses, and past that... projection room... (Like the x-men danger room)
"Look ma', no glasses!"
Really though, 3D just isn't ready yet. It's not a bad technology. It's not evil. It's just a chiseled stone wheel. You feel like you tripped back into the 80's idea of the year 2000 wearing glasses.
And 8K? Hey, cool. I thought we were just starting to touch 4k, but someone wants to jump the gun and skip over 4k... lets do it. Just don't be a sucker for full price 'this year's model' gear, and its good! Makes all the AVRs that dont do 8k cheaper no? eh, maybe I'm too optimistic?
