[...] There's no currently planned overarching limitations on any PvP outside of the battlegrounds, which would be outdoor "world PvP". You of course have rez-timers to compete with and all of the other inconsistencies that come with world PvP, and as stated in the change any one with the rez sickness debuff is worth no honor. I assume though, however, that Lake Wintergrasp in the WotLK expansion won't be a bad way to earn honor in an outdoor environment.
