From watching the talk, it seems they have rushed a bit and are not in a good place to release code, docs, etc. The speaker implied that fundamental pieces are still changing rapidly. In all that rush, I doubt anybody has the hours necessary to write a nice blog post.

It's interesting that they are making a private repo available to attendees. I suppose they want to get some feedback and start some hype but also want to ensure a smooth initial public release.

Perhaps some community members with access to the private repo will blog their own impressions, if that's not discouraged?
