Bungie stated that they were aiming for parity. Like I said, they made the PS4 version to a spec they calculated they could eventually achieve on XONE. They knew the MS team was helping and factored all that in.
It is pretty foolish to think that the PS4 could not push this a bit harder if Bungie wanted to.
Everyone, three things
A) A PS4 is not a super computer
2) There is no doubt it could have been pushed further, maybe the pre-order numbers stopped anyone bothering. You only have your selves to blame pre-order people.
and
D) It's cross generation, everyone and their cat knows that cross gen games always turn out like this, that's why both are 1080/30. If it was next gen only then the graphics and effects would have been improved and it would be 1080 vs 793 or whatever strange res the xbox would be given.
You come here for a bit of news and opinion, help you decide if the game is for you and you have to wade through all the whinging or deriding. The consoles have been out for 11 months, any danger of people just getting over it?
EDIT
Here is a cross platform/gen comparrisson, for anyone that is interested
