Technically, Goblin dancing already is breakdancing.

If you get the Goblin disguise at Halloween, and dance, they sort of breakdance.

The Goblin flightmaster in Ratchet is showing off the goblin dance, in case you don't feel like waiting another eight months appx. for next Halloween... :)

This is exactly why it's not gonna happen. Not unless they can make it so people cant hump things, which would be impossible.

Think about the idiots who spam Anal [Whatever] all day, now think about them running around in their skivvies and humping everyone and everything in sight.

Then think about the 6 o clock news reaction.

"Your KIDS are using a popular VIDEO GAME to simulate SEX, on the INTERNET! We'll tell you which one after weather and sports."

Blizz doesnt want or need that kind of negative press.

Right, because Blizzard clearly wouldn't cheap out and just give us the other races dance-moves.

You know, just like they did with the "New hairstyles".

I'm chime in with a meh as well about the dance studio. Now, special trainers that let you change your casting animations... THAT would be more interesting.
