I thought Cisco would wait until Cisco Live to do the announcement, but looks like they wanted to give everyone time to come up with some questions. I am curious if any of the hardware changes are going to slow down any of the training vendors in updating their material? The additional hardware seems to remove any option of a home lab unless you are just burning piles of money in your spare time already The additions of the wireless controller, and IP phone is interesting.
This is what I have been honestly waiting for to see if taking the 3.0 written exam is worth it, or to just wait for the 4.0 version to go live.
