I think we'd all like to see more stats like these. And I think there are opportunities for many groups, not just the Wikimedia Foundation, to do this type of research. For example, most of the current stats were collected by UNU-MERIT, an external organization. I think it was a good first effort with many opportunities for improvement.
A great example of research done with the Foundation and some folks on this wiki collaborating is the Former Contributors Survey Results. I would love to see many more folks organizing research efforts like these.
