A 64-bit client is now available for use with Patch 4.3.2. Before being able to launch WoW in 64-bit mode you will need to download the 64-bit client for PC/Mac (using one of the links below), and unzip it into your World of Warcraft directory. Once you extract the files you can start the 64-bit client by opening the Launcher as normal (Run as Administrator if applicable), go into Options -> Game Preferences, and toggling the Launch 32-bit client setting. The game will display which version you are using at the bottom left hand corner of the login screen. ex: Version 4.3.2 (15211) (Release x64)

Build 4.3.2.15211

Patch 4.3.3 on Live Realms (probably) this Week
The final version of Patch 4.3.3 (Build 15354) hit the Blizzard download servers and it means the patch will most likely go live this week. This build seems to be the right one (unless something terrible happens, as usual, but it almost never does).

This patch doesn't really have anything interesting for players, it's mostly a bug fix patch with a way to consolidate most of the Patch 4.3 hotfixes into the game files to display them properly.

If you are testing the 64-bit client, make sure to remove it before the patch, as it blocks the update from working correctly. You can find the full list of files to remove in the support article. There is no new 64-bit client uploaded yet, so you will have to make do with the old 32-bit client until an update is released.
