US: Free Character Moves
More free character transfers for US realms. (src)
We will be offering free character moves from selected high population realms to lower populated realms, assisting in population dispersal. The ability to move a character on the selected source realms will become available on Friday, January 4 at 12:01 PM PST, and are scheduled to run until Friday, January 11 at 12:01 PM PST.
In the event that a realm meets our transfer goals before the scheduled end date, the transfers to that realm will be disabled. We highly recommend that if you are planning to transfer that you do so at your earliest convenience. No characters will be eligible for these free moves once the transfers have been closed.
Once the transfers open you can begin your transfer by visiting the Character Move page located here: https://www.worldofwarcraft.com/account/character-move.html
The realms chosen consist of source realms with the highest sustained queues, and destination realms with the lowest population. The numbers gathered are directly from our data, and depict the realms in most need of these transfers. We will be continuing to monitor all realms and open additional free transfers in the future where necessary.

Arena: Season 4 (src)
I couldn't tell you what the plan is for Season 4 yet. Let's wait a little longer before we worry. You should have plenty of time to get the gear you want now and when we can tell you more about Season 4, we will so that that those of you who like to stockpile points can.
No plans to retune any of the TBC dungeons (src)
I haven't heard of any plans to retune any of the TBC dungeons (heroic or standard). Of course this could change though by the time Wrath of the Lich King launches.
Bug Fix: WoW freezing after switching BG (src)
This is indeed a known issue fixed in the next patch.
You should be able to work around it by closing your raid pull-outs before switching battlegrounds.
WotLK: Will there be a new mount in expansion? (src)
We have stated in the past that we don't have any announced plans to add another tier of riding skill in Wrath of the Lich King. While you won't be able to use your current flying mounts right when you get to Northrend, we plan to allow you to use them at a later point in time.
As a reminder, anything could be subject to change at this point.
