Elaborate viral hoax or next-gen viral ad, that Sony Rolly video has pretty much everyone talking but Sony. We asked Sylvia Shin from Sony Corporate Communications Europe about the Rolly, and while she confirmed she had seen it on Engadget, she of course would say nothing of its actual existence. She did say that rumors of such a device showing up at IFA or being associated with the new Walkman players were not true, so it looks like we'll have to play the waiting game on this one -- we certainly asked to be the first to know if Sony does indeed decide to announce such a product.
