I think something like the multiple crop options in the new D4 and D800 become quite interesting for this reason. You can be shooting with the compactness and simplicity of a prime, shoot your mid-shot, and with just a touch of a button, punch in for your close-up.
With options like the Zeiss CP.2s in F-mount, that becomes a very intriguing option.
Spot on, Grug! FF Sensor with crop options is an excellent alternative (as long as you are happy shooting 1080 and 4k is not imperative). I am tempted to get the D800 as soon as it's out for that reason alone.
