World of Warcraft changing racial issues?

I just found that is now capable of changing his career in WoW for $ 30. My question is mean, do you think you can upgrade to one of my 80 years in either a worgen elf? or is blizz going to put a restriction on this issue?

Blizzard said at BlizzCon, they do not know how to change course or work worgen Goblins. Currently you are inclined not to allow the change to the new races race immediately and wait until there are characters in racing again already. However, still under discussion and allow changes in May and worgen Goblins race immediately after the liberation of the disaster.
