I typically duel at the gates of Stormwind, or Orgrimmar depending on my faction, but since it is unlikely that these areas will be cross-realm, what do you think the new cross-realm dueling area will be?

I've always wanted to duel players from other realms, particularly during obscure hours. I really look forward to this!!

Also do you think that the Arenas will be cross realm? IE. The Gurubashi Arena.
