You guys are really underestimating how good higher resolutions look even below native res on a good 4K screen. This isn't like viewing 720p content on your 1080p TV.
Well, again, I rather just get a 1080p set. I would like to avoid 4K for at least another 3 years. But personally, for me, I'd also like to see the benefits of HDR. If I could get HDR on a 1080p TV, that'd be everything I need.
