Coursera is now in an enviable position among MOOC providers: they have more students than all the other providers combined (Udacity, edX, FutureLearn, peripheral players like LMS companies). At this stage, Coursera is most like Google in its positioning (edX most like Apple in its attention to detail and quality).
Coursera now needs to start thinking of itself like a platform or an app marketplace. Clearly and publicly define how partners can work with and share data, create an app engine that allows universities to contribute to the value of the marketplace by sharing their content creation and testing tools. At this stage, no other MOOC provider is as well positioned to take advantage of the value add from network partners. The end result would (could) be that we see an explosion in creativity in online learning as the central video/content presentation format of MOOCs needs to be challenged and rethought by a mess of creative folks.
