Anyone have the lg 65ub9200 4k TV?I've been looking at this TV online and a Vizio 65 in also,is 4k a dumb idea with no movies till the new ultra blu-ray coming later this year? Also wondering if the lg has HDMI 2.0,but then again isn't the new blu-ray going to be 2.2,what is a person suppose to do now if you want a new TV and want it to be ready for the future?sorry for long post thanks
