>>"Personally, I'd like to see something a bit more dramatic. How about a mirrorless successor with a really fast frame rate? How about a CX crop mode on the DX cameras? How about an electronic viewfinder with a zoom mode for precise focus? How about a long lens to replace the 80-400 with a compact 100-500 or something similar? How about an app based menu system with WiFi built into the camera? The good thing about Nikon's position in all of these technologies is they are existing technologies that can provide significant enhancements."<<
This is very close to what I would like to see. Not to sure about the CX (2.7x ?) crop mode. Having used an electronic viewfinder before on Minolta Dimage7 & Konica Minolta A2, there are several advantages to me. You can chimp without taking your eyes from the viewfinder. Now with a huge diopter adjustment, it is a real pain as well as time consuming to go from the viewfinder, putting on glasses to view the monitor, etc. It also allows you to keep the subject in the relative direction you're shooting. I don't chimp a lot, but sometimes it's necessary. Being able to zoom an EVF is a real plus for focusing, etc.
Mirrorless solves a myriad of problems. If this camera could continue to use existing lenses... I'm for that. Real Wi-Fi built into the camera would be good, particularly if it is DNLA compatible. I would also like to see a high speed memory kind of like a built-in SD. It could hold emergency images, as well as the apps you're speaking of. Maybe it cold hold U1-U10 settings that could be loaded. There will need to be something that can do all that the cameras in smartphones can do.
Maybe Nikon needs to comeup with an android based, camera-centric smartphone as well.
