Ice Cream Sandwich Caught On Video?

Or possibly tasty, tasty prank. Google's talked a big game regarding Ice Cream Sandwich, but up until now the details have been a bit scarce. This video claims to reveal a bit more of what Ice Cream Sandwich will look like.

It could always still be a carefully orchestrated fake (and a tripod wouldn't have gone astray), but this footage, captured on a Nexus S purchased through eBay and sent through to Engadget purports to show a couple of minutes of what Ice Cream Sandwich will look like. The 'purchased through eBay' angle raises my hoax-alert-ometer slightly; what's your thoughts? [Engadget via Phandroid]
