Personally I would just wait until the Vietnam expansion, the VIP map packs prior to the forthcoming pack 7, were just a case of them unlocking different modes (i.e. you can now play Rush mode on map xyz) on previous multiplayer maps. VIP map pack 7 would be the first one with "new" maps, even though 2 of them are maps from the campaign and the other two are fan favs from the 1st BF:BC game..that's not worth $15 to me for the VIP code to me.
