If Halo 2 and 3 were getting updates to the playlists and new maps I doubt they would ever die. At least not until a new generation. My opinion on Halo 2 vs Halo 4 can't be made at this point. I can't see Halo 4 being as good, but maybe it will surprise us. To say it's not going to be replaced is just blind nostalgia. Cod 2, Cod 4, and Halo 3 are all very superior games to Halo 2.
