Really? Low-end DSLRs should remain for the interchangeable lenses though, right? I mean, a COOLPIX can't do that.
Not yet they can't. Where else would you put a GF1 or E-P3 like Nikon camera? If Nikon goes the Leica X1 route and puts a large sensor in a fixed camera then why would low end users want a DSLR? Most never use more than two lenses tops. They just want a fast compact that gives great image quality with a good zoom range. They could care less if it's an EVIL camera or a DSLR. In fact most would prefer to not worry about buying and switching extra lenses. An EVIL camera is the best of both worlds.
An EVIL Nikon will make more money than an expensive high end "limited edition" digital rangefinder. If they call it a COOLPIX it will help boost the COOLPIX line which is what they need to do it. A pro grade EVIL compact camera however would probably not be called a COOLPIX.
If Nikon goes with a smaller new lens mount for this "EVIL" class they can still have adapters to use fmount lenses.
