As far as TV's I think when we reach 8k there will be a plateau for a while. When you make a 'retina level' display (one that looks very good close up) and it is still 8 feet across!
Now I would love to see flexible screens - so you can flatten them when friends are over and watching a movie. Then curl them around you for a good 180 degree screen when you game all by yourself!
As far as 'future proofing' I think it is really an advertising gimmick. Sure, you can try to stay flexible with your hardware and make it 'easily upgradable.' (I'm thinking PC's) But it really doesn't work - because the technology advancements really obliterate what came before.
For example: You can double the speed of the CPU - and pop in a new one that's great. But when the bus innovation (the highway it's driving on) is 4 times and requires a change in hardware more than just a CPU increase.
So in this example you could double your speed, but by a hardware upgrade increase processing power 8 times. That is the real innovation.
