Personally I think rendering resolution is also a design-choice, much like the color palette of the game or the flow of UI, or the target framerate. Yes a launch title would be more likely to fall into the trap of being "forced" to use it due to lack of time, but I see nothing wrong with developers experimenting, it's one of the major advantages consoles have over more open platforms.famousmortimer said:2. I did mention that sub-native res was both good looking (uncharted) and likely a symptom of launch titles.
Ultimately it'll be up to market to decide if resolution tradeoffs are worth while or not - eg. the biggest game series on PS3/360 by far runs closer to PS2 "native" then it does to any "official" HD resolutions. But then again, "native" on Vita does look more spectacular then 1080P does on a decently sized HDTV (let alone 720P).
