Not saying it won't be "Warlords of Dreanor", but every name that's been trademarked the past couple months ends up being "THE" new WoW expansion name on these forums, and then begins the cycle of people either hating or loving it and attacking people who think the opposite or still dismiss its validity.
The same people that are fighting and attacking people who don't think this is the name are the same people who attacked others with "The Dark Below". Just, everyone relax. Speculate, have fun, guestimate, but stop trying to act like you know everything and that other people are wrong for having a different opinion. Nobody knows for certain, and we've definitely had some interesting names thrown at us to work with. Just one more week and we'll know for sure! Be kind to others... anything could happen.
