Following other vendors, and engaging in more nickel and diming, VMware recently announced that VCP certs are only good for two years before they have to be recertified.
In the past this wasn't much of an issue since major release versions followed a 2 year cycle anyway (3.5 in 2007, 4 in 2009, 5 in 2011). So what if someone could claim to be a VCP 4 if the current version is 5. One could speculate that the major release cycle will now be longer than 2 years prompting VMware to institute a "pay up or else" policy to generate additional revenue from the cert industry.
