At the time of that video, the indexing team was still working on one (very minor, corner case) type of issue, but I believe that was resolved. I'll double-check with the indexing team, but at this point I'd say feel free to go HTTPS.
As always, I'd test it out first, ideally with a lower-traffic domain name. But if you like the results you get, you should be able to use our existing tools like 301s and rel=canonical to help Google discover that the site has gone HTTPS.
