As an early adopter of both the Fuji NEX (NEX-5) and Fuji X-Mount (X-Pro1), I really recommend you skip the first generation... or two. No matter how many engineers a company has, or how good and long their testing is, many problems will not be fixed (or even spotted) until the product is released and in the hands of people using it to make a living.
Also, what lenses do you really want in that system? If you are invested in the Nikon F-mount, keep your DSLR for now.
If not, wait for Canon's answer.
