TV Recommendation - Samsung KU6000 Series 6

Howdy

Looking at purchasing a new TV in Boxing Day sales, to replace my trusty FullHD Panasonic 50" ("dumb") Plasma that we've got a good 7 years out of. I've been wanting to upgrade to 60" but waiting for prices to drop to under $2,000 - which they finally have.

HN & Smiths City both have this Samsung for under $2k...http://www.harveynorman.co.nz/tv-and-audio/televisions/4k-uhd-televisions/samsung-60-4k-ultra-hd-smart-hdr-led-lcd-tv.html

Now, I appreciate it's not the latest & greatest, but at a glance it does everything I would need. UHD & HDR.My main question is: Is this TV missing anything that may be a big issue over the next few years?Still have SkyTV - mainly for Sport. Also watching more & more streamed content (via Chromecast at present).Not interested in gimmicks like 3D or curved screen.OLED out of price range.

Would appreciate any thoughts, cheers.
