Well, several hours after writing the story, Google indeed sent out the certificates to those who participated and completed the online Google searching course.
I have pictures from two people who completed the course, including Aygul and former Googler Pedro Dias. Pedro boasted that he scored 100% on the course. I'd hope so, you did spend several years working on the search quality team. :)
That being said, here is a larger view of the certificate:
I am not sure when or if Google will continue to offer these courses. Aygul requested "more advanced courses." From the looks of it, the course was pretty basic and any SEO should have easily been able to score a 100% on it.
