Got the PS3 version today.
After 2 hours and a couple more minutes, I might say it's a pretty good game. Sure, it feels like some kind of Bioshock in a wasteland with a shitty story but it's solid, it plays great, shooting is reeeally fun and satisfying. AI is great, enemies are moving a lot and trying different ways to attack.. in fact, they remind me of Condemned quite a lot.
It's also quite impressive since I've not seen any frame drop so far, except for a bit of tearing in some places.
Everything has a price though, it's a 8GB install and textures are popping-in all over the place. It feels a bit like a 60fps google maps ... anyways, it's still pretty damn impressive. If next gen games use that kind of loading, we could see some incredible visuals.
Also, the sound design isn't up to par, especially the music. I don't know how you can go from "Trent Reznor" to this... the game feels much better when the music is turned down to about 30% volume or less.
