I think they're disgusting, they look like those cheapo 3rd party controllers you get that always show up around big games, cashing in on the hype, which is essentially what these are, but they're real 360 controllers lol.
I think the green army looking Halo 360 controller looks better.
I was listening to one of Major Nelson's recent podcasts and he had an interview with the guys responsible for those. Apparently they are limited edition and there is only going to be one production run of them. If anyone really wants them they better get them now. I would be surprised if they sell out but you never know.
