VMware have now released the VMware Certified Professional - Desktop certification for vSphere 5 and View 5, shortened to VCP5-DT. The exam is aimed at those who are responsible for deploying, administering, and managing View 5 on top of vSphere 5.
There is no formal training requirement for View 5 to qualify for VCP5-DT, the View 5: Install Configure Manage course will be a big help, but you must hold VCP5 in order to qualify for VCP5-DT certification - and of course VCP5 does have a vSphere 5 training requirement.
So, if you're starting out with VMware certifications your minimum requirements to VCP5-DT look like this:
Attend vSphere 5 training > Pass VCP5 exam > Pass VCP5-DT exam
If you already have your VCP5 certification you will only need to pass the VCP5-DT exam. If you are a VCP3 or VCP4 you will need to gain VCP5 and pass the VCP5-DT exam.
VMware have not shortened the path to VCP5-DT for those that already hold VCP4-DT, and it now looks like there will be no VCA5-DT certification at all - VCP5-DT will be the foundation-level certification for View 5.
As usual, VMware have published a number of resources for the VCP5-DT exam - the exam blueprint, mock exam, confirmation of the various training/exam paths - here's the official VCP5-DT page:
