Whilst I've been speculating about the possibility of a Limited Edition Halo 4 Xbox for some time, I'm not convinced this is it. It doesn't really match the stylings of the previous two Limited Edition Xboxes, and the one in the background appears to have part of the "H" and "4" cut off. We can also see that one has a silver trim and one has a black trim, I think it's unlikely we'd see two variants of a Limited Edition console so it's more likely these two were modded for display as opposed to consumer use.
It could be a set of stick on decals like the ones which have been sold alongside previous Halo games, it could be a promo item given to retailers, it could be for a competition prize in the near future.
I still think we will see a Limited Edition Halo 4 Xbox, but I'd expect it to be more in-keeping with the previous two.
