The Anniversary Update is actually already available so I wouldn't be surprised if this is it.

You can still get the MCT with the ISO, Gary.

The download is located directly beneath the Update Now button.

This is great news and definitely good to know.

I'm going to spread the word.

Thank you @adacosta!
