Maybe they're just waiting for the TU to see if it allows more options for customization, since there isn't a whole lot they can do with the settings right now. I would imagine that they want to remove Instant respawn and perhaps sprint, among other things. If they like what they see with the TU, then it wouldn't surprise me if they picked it up again.
I do find it ironic that not too soon after Bravo starts working for 343, Halo 4 gets dropped from MLG.
I think you're misunderstanding: MLG didn't just up and decide they don't want Halo; a deal was signed with Microsoft and Virgin. Broadcasting, if Im not mistaken, is part flit the contract. MLG can't broadcast Halo it would seem, due to that infringing upon microsoft's deal with Virgin.
