After the gossip of Watch Dogs being intentionally hobbled visually to make the console version look better, Bungie has admitted Destiny's sticking at 30fps so all platforms will have "the same experience".
The comment came from senior environment artist Jason Sussman who said this to Venture Beat when asked why the studio was targeting 30 instead of 60fps:
"It’s a lot of different things. I could get really technical, but I’d bore you to death. A lot has to do with performance. We’re cross-platform, so we had to be very delicate with all four consoles, making sure they have the same experience, that it looks as good as it possibly can on all these consoles. A lot goes into that, from geometry to textures to post effects to particles to how many players you get on the screen. We’re always balancing that out to make sure everyone gets the same experience."
