We don't know the restrictions on faction changing yet, but when they do server transfers, they make you empty out your mailbox. You probably could put an heirloom from your Alliance characters in your bags then switch over to Horde with it, yeah. They might put a restriction on doing that though, who knows? You can probably do it but we won't know for sure until they come out and tell us.
"Are there any official lists of all the easter eggs/references to real life people/events in the game?"
There isn't an official list anywhere that I'm aware of, no. As many other readers mentioned yesterday, Wowwiki is a good place to check for that though, they have numerous lists. They have lists for pop culture references, in-jokes, and easter eggs.
"Break it down for me... What is going to happen to my old badges when 3.2 hits? Should I spend them now because they will be useless? Will I be able to use them in conjunction with the new badges?"
Your old badges will still be able to be used for everything you can use them for right now. All new items will use Conquest badges, and Heroics and such will only drop Conquest badges. If you're short a few Valor badges for something you want, you can trade Conquests down to Valors, but you can't trade anything up. Comprende?
"Since DKs have different NPCs when doing the four champion level AT dailies and get Ebon Hold rep instead of Argent Crusade rep, is the Crusader title based on being exalted with EH (for DKs), or do DKs still need to get AC rep as well?"
I believe Death Knights do need to grind Argent Crusade rep, yes. If I'm wrong on that, hopefully a Death Knight that has done it will correct me in the comments, but that's how I understand it. The achievement itself isn't any different for them, they just need to do it a bit differently.
"If I were to cancel my WoW subscription... does that mean all of my characters will be deleted? If not, what would have to happen for them to be deleted? Besides doing it manually, I mean."
No, your characters are not deleted when you cancel your subscription. You can leave the game for a very long time, and when you come back your characters will still be there waiting for you. I've had guild members come back to the game a year or two after they'd originally quit and all of their characters were as they left them. I don't think that Blizzard will ever take your characters away unless you delete them yourself or you do something to get banned.
"Why is there currently no water in Dalaran sewers on the PTR did they forget to pay their bill? Although they are mages, have they forgotten they have the spell conjure water or do they just not have enough mana left?"
There's no water in the Stormwind canals, either. Gasp! Could it be a precursor to the Maelstrom!? Are the Naga draining Azeroth's water supplies now, since they failed in Outland!? Was Serpentshrine Cavern only a setback!??
Nah, it's just a bug.
Jason P asked...
"How much wood would a woodchuck chuck if a woodchuck could chuck wood in Crystalsong Forest?"
None. They would break their little teeth! Woodchucks just aren't built to chomp magical crystalwood. Why do you hate the poor woodchucks, Jason?
