Dont have new WOD models

I just realized I have been playing on the new client (3.3.5a) but I dont have the new character models. I have re downloaded the new client but still do not have these models. People in the forums are always talking about these patches that should be in your data folder but I dont have the specific patches mentioned. ex: i dont have "patch-w and patch-x" or "patch-enUS-w and patch-enUS-x inside Data->enUS folder". Am I doing something incorrectly?

they have removed the torrent of Wotlk with WoD models (I guess because that client was too buggy)
