I like what a lot of you guys have said about it being obsolete when your creativity is limited or you can no longer do what you want with it. I feel that in some ways I've hit that point with the D7k and in other ways I haven't. Low light performance sucks massive rocks, but overall the camera still offers pretty sharp shots with the right lenses. That said, it would be really nice to have that extra "wiggle room" a higher-rez sensor would provide.
Agreed on this idea, that one's camera can limit creativity or potential images that can be made. And that newer, higher-resolution sensor can offer you wiggle room (and more). I've gone from the D1, to the D1h, to the D70, D2x, and D3x in Nikon branded cameras, and had Fuji S1, S2, S5 d-slrs, and Canon 20D and Canon 5D Classic. We have advanced a long, long ways in the 18 years since the Nikon D1 was released in late 1998.
The reallllllllly major breakthrough was the shift from a camera like the Canon 5D and its somewhat narrow dynamic range, and the D3x with like 13.7 EV total dynamic range, and just a MUCH,much,much better sensor, and better electronics. Moving from 10.5 total range to 13.7 was a huuuuuge difference. And the ability to recover over-exposure with the Sony-made sensor was a game-changer.
Today? The D600, D750, D810, all of the "new-generation" Sony FX sized sensors offer astounding quality in 35mm-sized cameras. And the D7200: the sensor shows almost no pattern noise in the dark areas when a 5-Stop under-exposed raw image is
brightened up in software. That's the major difference that I can see between the D7100, and the D7200: the newest sensors are basically ISO invariant. This is a major,major,major shift in the new Sony, Nikon, and Pentax cameras: you can now under-expose to a huge degree, to build shutter speed, or to get more DOF, or to protect briliant highlights--and then, you can "lift the shadows" to a huuuuuge level, and not have a ruined image. This. Is.The. Biggest. Advance. Of. The . Last. Decade. Achieving wide,wide scene DR through ISO invariance due to better sensors, and better in-camera electronics, and better signal processing.
This means that the Canon 5D Mark III loses real DR to a Nikon D610 or D750, or to a Sony A7r series camera.

Compare the 5D Mark III with 11.7 maximum EV to 14.5 EV to the D750. WHO wants to throw away almost three, full EV?
I dug out the Nikon D1 last year. Ugggggh. Wow. HORRIBLE dynamic range. Awful. Low-res images, 2.7 MP. Weird color response. Truly, not a camera I want to use.
