The last I heard, in another thread a while back Brandon asked around and one of the environment artists may have indicated that one of the maps he was working on was designed with the intent of it being used as a pvp map. Didn't specify space/lolground.
Of course plans change etc, so we'll see.
I won't be holding my breath waiting for the new PvP map to be released today because I suspect I have more chance of flying to Mars and winning a trip to Vulcan in the Mars national lottery.
What I suspect is more likely to happen is that we either don't get the new space PvP map (what point is there in releasing a new LOL ground PvP map), or the map is released but only available to those players who have won access to it in a newly created Dominion Gold lock box, which of course will require a master key costing 400CP to open.
