TOPIC: How to study for 6th edition (exam after 28 Mar) with existing prepcast?

I purchased PM Prepcast as the website says it will be updated in Feb. It is not updated until now and no confirmed date on when it will be released (I thought a PM company should be more organised and have clear plan and communicate how to deal with the situation ) . SO - I am not sure what to do now.

Can someone please assist me with below questions to prepare for my exam:
- Will all new videos be uploaded and existing removed? In this case, is it not worth wasting my time watching the videos now and wait till then?
- If I already watched all existing videos by then, will you give a summary of what change from the 6th ed so I don’t have to re-watched another 35 hours? How will the update be implemented?

Thank you very much.
