We've gotten some of the basic questions answered, here's some of my burning ones still:
--When will the sharding at release be deactivated?
--What, if any, specific balance changes will be made?
--What, if any, bugs will be fixed?
--Are there any anticipated problems / bugs from the game residing on the 7.3.5 engine?
--Will there be seasons?
--Will there eventually be progression to BC?
--What reunification efforts will be made?
--Will people have dibs on old toon names?
--Will Molten Core or other earlier raids be tuned up a bit to compensate for threat gen and DPS gains by patch 1.12, plus Dire Maul gear?
--Will server merges be announced ahead of time?
--Will group-finding addons be allowed?
--Will any addons legal in 7.3.5 on live not be allowed in classic?
--What armory functions will be available online?
--What will server population be?
--If server populations are different from classic, what will spawn rates of mobs / herbs be changed to?
--How will it be communicated to players that did not play classic that performance of various specs wasn't balanced to the level it is now?
--How will griefing on world bosses be handled?
--What will the names of the servers be?
--What is the anticipated number of players in the first few weeks?
--What is the anticipated number of players after the first month?
--Will the old old mounts be available?
--Will special characters be allowed in names?
Answered Questions:

--Battlegrounds will be cross-realm
--Dire Maul is in the first round, so that gear will be available immediately, correct?
--Loot trading will be available
--Server transfers will be available
--There will be an AQ event
From other posters:
--Will the nights be dark like it used to be?
--Will the geometry of Maexxna's room be fixed?
Random stuff I'm not making a separate thread for:
Any chance at non-1.12 Alterac Valley?
Will it be made clear what servers will be merged (edit: connected) when the time comes? Something like "Frostwolf 1" "Frostwolf 2" "Frostwolf 3" with unique names on all 3 versions so when they're merged there's no conflicts. Or even just indications of which servers will be merged when the time comes.
