Unless this is some cruel hoax, here is the interview where he mentions it. Glad to see pvp becoming a bigger focus in the game.

Q: Are there plans to hold an official tournament, then?

A: Of course there are. However, I think that the two spectator modes I talked about earlier would be absolutely necessary for this, so we have to finish those first. We're also going to make a mode for 1v1 practice duels, as well as a mode for team practice matches. This will give people who are afraid to queue in DF the ability to practice beforehand with friends to get a feel for PvP battles. After the spectator modes and practice modes are ready, we can move towards official tournaments.
