So while doing a little investigating on the Barbarian, I ran across an interesting tidbit. Let me preface this by saying that I usually don't trust anything from wikipedia but for the sake of discussion I figured it was worth it.

"...but former classes may appear in future expansions."

That is a direct quote off of the wikipedia D3 website. So I guess there are two points of discussion. Number one, would you like to see older classes come back in an expansion and which ones? Number two, has there been any talk of possibly delivering an expansion or is it just speculation.
