That list contains a lot more than just achievements to be added in 4.3 it seems.
Most of the 4.2 ones are included too.
But it can be used as a reference, yes.
I am NOT looking forward to the Darkmoon achievements. Can you imagine 8,421 toons trying to do the Gurubashi arena style event for "Darkmoon Duelist" and "Darkmoon Dominator"??
