I think its time for a change of pace, and have been thinking of this for a few months now. Im going to hold off (maybe indefinitely) on the CCIE, and focus on a CCDE attempt.
My reasoning for this is my growing interest in design material. I really enjoyed the CCDP objectives, and my current job focuses more on design than 'break-fix'. Thats not to say that the CCDE does not require an extremely in depth understanding of many of the technologies that the CCIE tests on, I just feel the design objectives are more suited to my interests, and where I want to take my career.
That said, there seems to be an utter lack of interest in the CCDE track overall. Perhaps some are 'offended' that Cisco claims the CCDE is 'above' the CCIE, but I disagree with this anyway. Its not better, just different

Perhaps some people were bored (like me) with the CCDA so much, they never looked farther. Or perhaps people just don't like the network 'fluff', and rather focus on the 'meat and potatoes' of configuration.
This will present challenges in finding material, and general support of past candidates to get an understanding of the exam. The idea of pioneering this though is a challenge I am looking forward to.
As for timeline, it really is not set. I am going to start researching the written objectives more and compile some material, starting with their recommended reading list. Im looking to take a Data Center Design course soon, so perhaps I will pick up some of the design specializations along the way. I am also taking project management classes and maybe ITIL later this year, so I hope to blend as much as I can from these (and vice-versa).
I will try and keep my progress up to date here, or maybe even start a dedicated blog offsite for it, as its tough to really find a good source of info on this exam so far.
Upward and onward!
