Likely will just look better and have a more stable framerate, but it's on a game by game basis.
Some games do offer drastic changes like playing in 60fps or unlocked frames mode, versus 30fps and that's a big deal to a lot of people.
The entire argument Colin made ignores a big portion of PS4 users who do care about frames and resolutions.
I certainly don't care as much as some members of GAF in every DF thread talking about dips in frames etc...but to basically say "this is stupid Sony, no one cares about better resolutions until it's a huge jump just focus on games" has to be the most opinionated thing on gaming I think I've ever heard. It's just dismissive, and it's not good to feel like you are part of an audience being made fun of.
Greg "the frames, and the rates and resolutions"
Like we get it, you guys don't care, but people that do aren't some weirdos either, lol. Games just feel smoother at higher frames and people like it. Also stuff like UC4, that's all about storytelling greatly benefit from higher resolutions and overall graphics being better, it's a very important part of ND, PD, GG games and those devs are excited their work gets presented in a better light.
I'm sorry, no one is saying anyone should be excited over something they don't care for, but the posters who come up with arguments that they shouldn't tone it down and be a little more unbiased for the fans that are excited have presented weak rebuttals.
