If you care at all about that, what do you want from the D750 successor ? I myself: - Price: I guess my personal limit would be about 4k€, above that is my cutoff. - Size/Weight: Frankly, if I can get larger AF area and a silent shutter for that, I want to go back to the D600 size. - Sensor: Well Thom Hogan is wrong, the resolution needed for "perfect" 4K would be 45 Megapixel (8192 * 5462 = 44,744,704), not just 33 Megapixel. Though I guess many will be perfectly happy with UHD (4K: 4096x2160 at 24 Hz, UHD: 3840x2160 at 60 Hz) already. Personally I much rather would want 12 or 16 Megapixel, excellent pixel quality including good color at low ISO and excellent reserves in high ISO, and high fps instead. Native ISO 100k would be perfectly sufficient, I dont need any of the expanded modes after that. But oh well, realistically I expect native 25k and expanded 100k this time around, and again 24 Megapixel. I guess thats fine. - New D5/D500 Autofocus: Why yes, I would like to live on the bleeding edge of Nikons autofocus system. Especially the larger AF area gives me a huge WANNA HAVE WANNA HAVE reaction. I dont mind so much that its mostly left/right (in the standard landscape orientation): thats understandable given the technical limitations, and I mostly miss the space in portrait orientation, anyway. - Ergonomics: Pretty pretty please get rid of the completely idiotic policy to enable the monitor when one changes ISO !!! Who even came up with this silliness ? Seriously ! Oh, and a separate AF-ON Button would be nice. And give us at least one more U mode. And make U modes save everything, just like Canon does since ages; for example I would like to be able to configure U1 to video at 1080p, U2 to video at 720p, U3 for sports, as quick selects to react to a situation. - Touchscreen: One of the biggest issues I have with the D750 is that Lifeview is really useful, especially for focusing in low light or when I use the tilting screen, but choosing the AF point is hella slow. A touchscreen would be really, really helpful there. - Fully articulated flipscreen instead of just an up-down tiltscreen: despite careful handling, my D750 screen already has minimal scratches. My D5100 was perfect until the end. So yes, I want a full flipscreen again. Also the effect would be that many controls move to the right side, which makes them easier accessible. - Shutter: silent, more silent, completely silent. Give me a silent shutter in the first place, electronic first curtain, and fully electronic in mirror up mode (just like D5). Thanks a lot ! - Video: Nikon is so far behind a GH4 its just not funny. I wont hold my breath there for good video from Nikon. They'd need focus peaking, full readout, 10 bit recording, ... fortunately I'm not into video that much in the first place. - Memory cards: Again 2 of same type, with backup mode. I would like SD with UHS-II support. - Build: No wishes there.
