In the court documents that John R Troy kindly provided us with, Wizards have stated that the first print run of the Player's Handbook 2 sold out, and the core 4e books are currently on their third printing (and have sold hundreds of thousands of copies in total).
It's estimated that about 6 million people (worldwide) play D&D.
