After seeing the 4k demo at Yodobashi Camera in Kyoto in December, I am holding off until I can afford a 4k TV to buy my next TV. It really makes a huge difference and is quite a large step up from 1080p.
Of course, content is an issue, and it probably will not affect gaming, even in the next batch of consoles.
Also, I am a little worried that older films will look "too good". It will look AMAZING for sports, documentaries, and newer films though.
