4k resolution is coming and coming fast. Sony's XBR-84X900 4K LED TV $24,999.99. Yeah wow that's expensive, but it's a good sign. within 4 years these things will be pricing closer to $2,500. Not to mention feature stripped versions in the $1,000 dollar range. At least 1080P won't look like crap in 4k TVs like 480p does on HDTVs.
Theirs a difference, when 4k really starts happening it will be 2014, if the PS4 releases i will most likely be the only one doing it while the Wii U and Xbox 720 are 1080p, but it won't matter because no game next gen will be native 4k.
