Patch 4.3 is the hot topic for all of World of Warcraft players right now as you try to divine what will be in patch 4.3. Players are just curious about what will bring in patch 4.3 and most of the content in patch 4.2 has already been completed.
Patch 4.3 could include new 5-mans, or new daily content which is unlike the Molten Front. Players could even see a tier of raiding pitting players against Deathwing himself soon.

Currently, the PTR is up to patch 4.2.2, so there is no new content. World of Warcraft players hope after a round of clean up and bug fixes on the PTR then players could get some news about patch 4.3 and the wonders. Let’s see the main changes in patch 4.2.2 first:
