I did not read through all the comments to see. I played a demo of HAZE at PAX and I was not impressed at all. It was a 4 person co-op demo. The graphics on the two stages we played were really bland. One stage had us in some sort of driving vehicle (much like a jeep or something) with one person driving and everybody else shooting. The second stage took place in a building complex with multiple floors.
I know it was just a demo but the stages they showed at PAX was not the be...
I'm not sure about specs but the whole controller thing is BS. I've played the game a week ago at the World Cyber Games and they had a station setup to play with a 360 controller. The game auto recognizes the controller. It plays very well and would take no time at all to pick up the game playing with a controller.
Now will the 360 or PS3 be able to run the game in it's current state at all, well I don't know. But I do know that the controller "issue" is not an issue...
Sounds pretty cool. Hope it plays well.
