Do you think Nikon could challenge the X system with something like this (pix)?

I agree.

I think Nikon's One system has very innovative, and underrated, features that people fail to mention.  All people talk about is its 1" sensor, which doesn't take bad photos. It's only bad if you want shallow DOF all the time.  You can always get narrow DOF if you focus in close enough, so I suppose it's just the inability to get narrow DOF at longer subject distances that's the problem?

If the Nikon One system had an APS-C sensor, it would arguably be the best camera on the market.  Well.....it would be better than Sony NEX, which many people seem to like.

Fuji has my money due to the ergonomics, prime lenses, and hybrid VF, but I suppose I could be lured into using a Nikon if it was great.
