The biggest victim? Shadow detail, as evidenced in this thread on NeoGAF. The amount of enemies onscreen, however, apparently doesn't drop so there should be parity between the two versions in terms of how the game actually plays.

Considering that the PS3 is almost eight years old at this point, however, it's kind of a miracle that it's even capable of playing something like Destiny to begin with. And given that there are likely well over 80 million PS3s in the wild at this point and, as of April, only seven million PS4s, it makes sense for developers to continue supporting previous hardware. Take this April's Watch Dogs and next year's Mortal Kombat X, for example.

What about you: is Destiny the game you're upgrading to a new console for (maybe even a white PS4), or hasn't anything on Sony's latest or the Xbox One caught your eye yet? The beta is down for maintenance now anyway, so you should have plenty of time to leave us a note!
