I appreciate the people who datamine and test these things. 
Not because it would be important (the update comes when it comes, how it comes), it just sounds like a fun hobby and a cool attitude.
Like “I don’t know what dataformat it is but let’s just poke it with a stick (Tar? Zip?) until something comes out (xml? Json? Psarc?), and then poke it some more” until it turns out to be a jetpack or the suite voice or what ever.
