I know, LMS is probably not the most popular thing to discus here, but: http://edutechnica.com/2013/11/16/top-lms-news-of-2013/
Open Class sounds interesting, worth investigating a little.
I like the look of Open Class and was a little surprised to see that it is a Pearson project. That doesn’t rule it out, but it’s worth keeping in mind. I have had a number of conversations with Pearson (they are a member of the Media Lab) and they are definitely interested in figuring out how they can provide services / value as more and more content becomes open.
