It's annoying how the "Vsphere4 Install & configure" course is available right now, but the "Vsphere4 fast track" isn't going live until Q4 2009. I'm going on the "VI3 fast track" next month. I asked if I could wait a few months and do the "Vsphere4 fast track" course, but they're really pushing for more virtualisation at our place atm and said it can't wait. So it was either "VI3:fast track" or "Vsphere4 install & configure", and I see the fast track as more valuable. I'm guessing there's a *lot* of overlap though, and hopefully it will be fairly easy to go from VCP3 to VCP4.
