On March 23rd VMware officially announced the retirement of their VCAP5 Datacenter exams. Read the official information here: 4 Exam Retirements in June.
It's an interesting move as the VCAP6-DCA and DCD exams aren't even available to book right now. You can still book and sit the exam up until the expiration dates (June 4th for DCA, June 24th for the DCD).
I expected this but am a little disappointed. I booked my DCD for May 27th with the backup plan of taking a second shot at VMworld should I need it. Now to comfortably get a few shots if needed I need to move it up to the middle or end of April.
