From what I've seen, the game is a lot less pretty than its original reveal
Video game devs/publishers have been doing this a lot lately. They "reveal" the game, and it looks spectacular, almost like nothing you've ever seen before, then a month before release they show you some footage from the final version which looks like shit compared to the original reveal.
One perfect example of this is the game Watchdogs, if you look up footage from E3 last year then compare it to recent footage... the difference is undeniable. It's misrepresentation at it's finest and I'm not sure how they're getting away with it. I don't play games for graphics, so I don't really care, but it's still a sneaky business practice.
