"TBH I don't really see the point in this until TV stations start broadcasting in UHD.
I'll wait until then and buy a technically more developed TV for a lot less."
Hope you plan on keeping your TV 20+ years, HD broadcast standard is 720P. 10 years after 1080p was introduced as the BluRay standard there are still no stations that actually broadcast at 1080p resolution. The problem being bandwidth and the antiquated systems that exist for transfering information to our TVs. Untill everybody has a direct fibre link in their homes Beroadcast TV is going to be stuck at 720p.
That being said, 4K/UHD will still become the display standard just as 1080p did. Try finding a panel bigger than 32" that is still only 720p.
Would imagine that by the time 1080p becomes a broadcast standard, we'll all be buying 16k TVs.
