Don Jones has just made it official HERE: Microsoft will be offering an official course on PowerShell v2.
I have had the honour on working on some of the labs for the course, and I think it is going to be a great course packed full of information for beginner and even intermediate PowerShell users.
I definitely agree with Don on his statement about how beneficial having a experienced instructor deliver such a course.
Books can be a struggle, but with a in-person course, you get to ask all those questions that may be lingering in your mind or they may be able to approach a concept from a different angle to help you understand all the important topics/concepts.
