Matchmaking Party system?

In Halo 4 does anyone know if there will be a true skill rating again or at least if you’re in a party you have to search for other parties (like Halo 3) so you’re not playing alone and matched with Teams of four. I am not sure if anything has been said about this but I’m doubtful because of the fact that people will be able to join in and out of games at will. Please implement something at least with popular play-lists or MLG.

i dont usually bump but… i gotta know. sooooo
