I'm sure it didn't say anywhere at the start of this topic that there would be a new topic, I haven't bothered to check properly though, so i'd expect someone to correct me.
If it has been stated, then I think whoever said it meant that PvP itself isn't going to be replaced, just the PvP NETHER map.
Cheers
Of which, i've posted a poll on the size of the new Nether.
