You know, I can't really say that there was an outright crappy map in Halo 2. I don't like big maps, but still regardless I was happy with them all! I think in reality, they owe the fans and supporters of Halo. They should release most, if not all the Halo 2 maps to play in Halo 3. Of course, all the hard work on the new levels would somewhat go to waste, so don't expect them to do this for a while.
