I agree, this is urgent!  To add to a couple of posts here also, winning the war is not the objective for a large percentage of players.  Making the bases harder to capture, and limiting the play time, has to further decline the probability of a map reset.
I am for the "scheduled" map rotation idea, but I am more in favor of game play that offers the strategic minded player, meat and potatoes towards a goal that may stand a chance to benefit his / her country mates.  
Two possible types of changes to increase the possibility of player map resets:
1-  Change the criteria, for awarding a map victory.  (Lusche has detailed one such plan)
2-  Change the criteria, for awarding base captures.  (I favor this type, especially if troops were given more of an important role, see this thread)
