1080p is quite popular on many PS4 and PS3 games. 4k isn't a must nowadays, but if you have the cash why not future proof your investment? I mean people that buy TVs at the $1000 to $3000 range don't buy a TV to replace it every year. The Sony 4k I just bought replaced a LED LCD Toshiba I purchased 4 years ago. So I probably will not purchase another for another 3 to 6 years. Why not get the goodies now?
