Impressive, to be sure. But terms like "anything" and "ever" are hyperbolic. Flash isn't going anywhere for years.
The thing that really struck me the most about this is that as little as 2 years ago there would have been absolutely no chance of deploying a huge brand interactive experience without Flash.
This is the first time I've seen a site that I thought was obviously Flash only to right-click and not see "Zoom in". I was pretty gobsmacked.
