I wonder if this might be a pattern this gen. Devs want to do more with the new consoles than just put out games that run at 1080p 60fps. They want more realistic graphics, particle effects, lighting, water, more things happening on screen, bigger environments. With all those ambitions the hardware still won't quite be up to doing all those things and 1080p/60fps. Personally I like that sort of compromise, lower the output but put in more details and realism. Heck I'm pretty happy for games to stay at the current 720p/30fps if it gives us more awesomeness in other visual aspects.
