Instead of selecting a pre-made character through Battle.net account you can now create a level 85 character of any Faction, Race and Class through the character interface, which says "Template Character" once you have logged into your BETA account.
This makes the experience much more enjoyable, the only thing missing in my mind is the choice of what professions your character should have pre-installed. I created a female Pandarian Monk (Level 85) however she was pre-installed with Jewelcrafting and Enchanting. Neither of which I have any interest in whatsoever. Its most likely that Blizzard are working on these two professions currently and therefore prefer the newly created level 85 characters to have these professions. Either way they can be changed at anytime you wish, however you will have to learn new professions from scratch.
