I am going to start it in november-december. There are two goals - to earn 40 cissp cpe and start my oscp certification process. I will prepare myself to it, studying linux, scripting and so on. So I will stay tuned. Good luck to the topic starter!
I see some people with ceh or oscp status here going forward to the cissp certification, great. As for me, I'm trying to start learning all that EH stuff to become one day a pentester, but what a tough thing...
It seems it's easier for a ceh/oscp to become a cissp, than vice versa...
