Anyone else notice possible 4th class hint here?

[Avalon-11311]

We had one going about the Paladin in the Lore section.

Are the Paladins going to be in D4?

Some feel that the paladin will make a return in D4 at launch. It was my understanding that the Paladins went West to Westmarch. The Crusaders went East. The zones in D4 are in the East, so why would the Paladins be in D4? Are the Paladins even around by the time of D4, lore wise?
