We really dont know whats going on behind the Scenes and i guess there is a good reason why the Video havnt released for now !
Maybe they are busy for produce from the beginning on more episodes so they have a few series that Cyrus can release them weekly or monthly.
If there is only one i guess there will be questions about the next one , i also can think about that they doing theme to have a Guideline from start.
But yeah thats only my thoughts , possible we get a early Christmas gift .
