Hi Robert — we’re confident that a lot of the content (mine specifically) will be added before end of December. To give you some context, I’ve personally added 3 lessons to my course today (Adv Networking). I have no doubt mine will be ready well in advance. The Security course has been worked on for a while already and has been released on day 1 with more content then the others. Sanjay who is handling the big-data course is a subject matter expect in the space and i know he is actively working on it based on the lessons we learned during our beta exams.
The only reason we didn't have content last week was because we’ve all been in transit to and from re:Invent.
Hope this provides some confidence ?
