Any estimates on when new Unity Certification coursework/exam becomes available?

I'm planning on studying up for the standard Unity Cert exam, and was curious about a couple things:

• Has anyone at Unity been able to confirm a release date for when the various tracks like programming and art become available?

• Similarly, are there any estimated dates for when online exam taking will be rolled out?

It looks like there hasn't been much news on it since April, so I was curious if there's any updates coming soon. Thank you!
