Here's my question... What happens when 4k televisions become the standard? It's not that far off, in my opinion. What's more concerning is that these consoles are at the very beginning of their lifecycle, and their barely able to hit 1080. Are we going to have to suffer with an upscaled 900, or 1080? I feel like we've hit a wall with regards to the leap in console tech. Seeing some of the launch titles on 360, and ps3 compared to xbox, and ps2 was like night and day. I'm not seeing anything "amazing" with xone, or ps4.
Ideally, video games should ignore 4k completely. The constant increase in resolution makes sense for film and TV shows (and therefore for TV screens, since that's what they're mainly used for), but it's just about the last thing one should be concerned about when it comes to video game graphics. In film, there aren't really many other visual improvements to be made -- in video games, however, we have to think about things like frame rate, animations, textures, model quality etc. and all of these, as I see it, are way more important than resolution. Even the most technically impressive video games running in 4K look less "real" and natural than any live-action film being shown in 480p, and the disproportionate focus on resolution in video games only means it'll take longer to close that gap.
I'm not saying we should be playing games in 240p in 2014, but I'd be completely fine with 720p remaining the standard for the next decade at the very least. Not that that's going to happen.
