The 2007 PDC is cancelled
Microsoft just released the news that the Professional Developers Conference 2007 (PDC) is canceled and will be rescheduled at a later date. As a reason they give that there are too many products being released at the end of this year. According to the announcement the PDC, focused on future technologies, should be held at a later date that is better timed for future technologies. No date is given though.

Guess that makes the choice between the PDC in October and the TechEd Barcelona in November an easy one 
. Still too bad because the PDC is always an exiting event.
