On the main topic, I won't be surprised if next patch is the redemption of Sylvanas "throwing off the chains of her oppressors". We probably don't kill the jailor, but instead purify him and make him realize he was performing wrong-think. Next expansion is going to be "World of Peacecraft", with cross-faction becoming available after we both experienced what death was like together. BG's can turn into cross-faction co-ops such as a race to burn the flags, obviously symbols of hate and oppression. The end boss will be a giant orange man who wants to keep the factions separate.
I almost want to say I'm joking, but at this point I wouldn't feel leery about betting real money on some or all of these ridiculous changes.
