Most of the stock WAR maps are not even 16 player capable. Their Node count is not high enough to properly support this many. Look at the map guides from any of the 32-player ONS clans.
UT3 with 64 players would be great, but it would require some re-tooling of the vehicles and layouts to support that game style.
As I mentioned in another post, Warfare should have been 64 player with UT3+BF+Tribes style play thrown together: troop transports, deployable pickups, player classes, etc. It moves away from the original "tournament" but it also moves into where much of the current popular games are oriented.
