Even though it was announced a few months ago, the first batches of DURA-ACE R9200 12-speed Di2 shipped to buyers and dealer just this week.
A couple of YouTubes have gotten their hands on it, so here is a quick overview of their videos.
First of all, Rides of Japan bought the full DURA-ACE R9270 launch edition and goes through the new steps of the build process in his latest video. He also weighs every component, if you're into that ;-).
Besides this build video, there will also be a long-term review at some point... so definitely keep an eye on the Rides of Japan channel.

Jon Maloney runs a relatively small YouTube channel - 5.86 subscribers at the time - but it's definitely worth a look. He (and his wife) upload a new video every few days, and there's a bunch of DURA-ACE R9200 content.
