Wayne,
The Agile PrepCast is primarily a PMI-ACP Exam Preparation Course and it is based on the PMI-ACP Exam Content Outline. Being able to use it to claim PDUs is really just a "secondary benefit". And so... unless PMI changes the exam content outline and includes more leadership/strategy as part of the exam, then we will most likely not be adding additional content.
That much said... I do have plans of creating a "60 PDU Package". This package would bring together webinars from multiple of our courses and will be aimed at earning all the required 60 PDUs including the required minimum of 8/8/8 PDUs for each of the talent triangle. But this idea is less than 24 hours old (it was developed at our annual company conference just yesterday) and we have no additional information about how, what, or when. More shall be revealed once we are done planning.
