No games will be 4k for some time ...
4k is 8 times the resolution of 720p, the PS3 rarely had games that could support 720p@30fps, and you would need a system that had greater than 8 times the processing power of the PS3 to support 4k games with similar detail and effects of a PS3 game. In other words, the most powerful system that Sony could realistically produce could play games that looked (essentially) the same as PS3 games but could output the graphics at a resolution almost no one has a TV that will support; and (likely) the majority of consumers won't have for 10 to 15 years.
