I'd say almost all engineering will be in demand - except petroleum engineering. What I'd focus on is what tools you think will be important 10 years down the line. With that said I'd suggest 2 things. Firstly I would learn tangential skills related to your discipline. ex. welding & machining if you're a M.E., construction technology if a C.E., etc. Secondly you need to earn to program and not just the shitty 1 semester "Intro to Java" class for the degree requirement. Basic comp sci skills is going to be the new calculus for engineering going forward.

Oh and don't ignore your soft skills. Proper report and memo writing along with public speaking will get you further then you can imagine.
