The problem is multiplat devs think we prefer 60FPS <1080P over 30FPS 1080P
Bungie hit the mark locking Halo 3 to 30 FPS in favor of graphical quality on the Xbox 360.
Another benefit of 30FPS is it makes some games look more fast paced in a good way.
Also I think devs try to build for PS4 first because they want to make the best graphics they can, though from what I've seen the improvement is marginal, even the difference between 8th gen consoles and PC graphics is marginal (4k is a trap) so they may as well just develop for Xbox One first.
Also, I think the problem with Skyward Sword is actually that Wii component isn't as sharp as GC S-Video (GC S-video looks amazing on my 1080P 32 inch). Personally I didn't mind it, my TV seems to have a very good upscaler.
