Step Up Revolution = Breaking II Electric Boogaloo

This — seriously — is the plot of "Step Up 4" aka "Step Up Revolution": greedy developer wants to tear down local neighborhood in Miami to make way for a fancy hotel.  Dancers organize to stop him… using the ultimate weapon : their sick dance skills.  Oh, and the female lead dancer is the daughter of the developer.  But how they succeed?

Actual line from the film: "We need to stop him.  Enough with performance art. It's time for protest art."

Wasn't this the exact plot of "Breaking II: Electric Boogaloo"? Or countless other song-and-dance films in the 40s? All this movie needs is Judy Garland and Mickey Rooney saying "Let's put on a show!"  

There are a lot of talented dancers and choreographers associated with this film: Adam Sevani, Twitch, Madd Chadd, Phillip Chbeeb, Travis Wall, the Ticks, etc. I'm hoping that the super-hokey plot doesn't take all the air out of the amazing dancing. But I have a doubt.
