I have been studying really hard for this, with a personal goal to certify on the new vSphere line by years end. Today that came true, with God by my side. The exam, about 85 questions and 90 minutes to complete, I had about 10 minutes left. This was a much more reasonable # of questions than the 270 we had in the Beta exam.I have posted earlier links to the study material I used. The vreference cards and Simon Long (http://www.simonlong.co.uk/blog/vcp-vsphere-4-practice-exam/) practice exams I think were very helpful in giving me confidence.
Good luck to you all going for your VCP certification! I'm off the donate some $$$ to simonlong.
