I kind of think the GXR system is insane. Coupling the 2 most expensive components of a camera system together means it'll be expensive to upgrade, and you don't get the benefit of seeing new life from all your lenses by updating the camera body like you do with DSLRs. What do you all think?
Would you like Nikon to come out with a system like this with lens/sensor combined? Or would you want a more traditional micro 4/3 type approach to it?
edit: here's an introductory video to the GXR if you haven't seen it yet
edit2: since the video's gone, here's the DPreview thread for some more info
