Sony to make something even more fantastic than Honda Grrr?

Rumor has it that Sony has made a film "even better than Honda Grr" - and those are some big bunny-shoes to fill. Rumor further stated that Fallon London hired director Nicolai Fuglsig to put it together, and a lot of bouncing balls were involved.
Now the only thing that seems to fit the bill are these thousands of bouncing balls raining down Filbert and Leavenworth in San Francisco this summer, a shoot done for a Sony commercial as stated at the internet archive where there's even a few films of the balls going downhill. Check it out.

Now, the question is, are the balls advertising for Sony music, Sony TV, Sony MD ... Sony, I dunno, balls? Hat tip to gossipers Jasper and Stacy. More flickr images here.
