They did and I updated and play the game. Too much of matching up against MUCH better players. I'm going to take a break from Halo 3 for a few days and let those better players rank up so I don't have to be stuck facing them. I'll play social games with friends when we can fill up the players list so there's NO chance of playing harder players. Might even get a chance to get some of the new achievements this way.
BTW, there are 6 new maps that will be coming out.
This info was gleaned from the list of ALL of the new achievements. In that list it states getting skulls for the new mythic maps, listed as:
Assembly
Citadel
Heretic
Longshore
Orbital
Sandbox
