Avengers / JLA!

I'm a little behind the times, but I finally picked up the second of the JLA / Avengers crossover books. It had Galactus in it! Woohoo! And a possible reference to HeroClix - in one panel, Superman says "in our world, the dials go up to eleven!" I'd like to think he was referring to the fact that DC HeroClix was the first set to have an 11-slot dial. But I'm crazy like that.
