How could anyone write an analysis only a few hours after such a complicated technology is released? It's also full of IANAL and yet still FUDing about how it's probably full of patents (as if google was dumb enough not to check patents). It looks to me like he had his opinion already formed on his previous use of VP8 and just published it today on time to make a big splash.

Edit: it looks like this article was released a few minutes after Google announcement...

Edit2: it looks like he had access to the spec a few days ago. I still think that Google is not putting their money blindly into VP8 though, they have the money to pay hundreds of analysis like this one and they sure did a lot of them, so it's either good enough or they have plans to make it good soon enough. Still better than x264 for people involved in free/open source like me.
