And further, it allows you to see what is about to enter your frame and focal points prior to it entering allowing you to better anticipate action as it approaches.

I don't see your point here - if you were shooting un-cropped the pictures would be the same but with more around the edges of you or subject and surely you are less likely to accidentally crop part of your subject out of the picture if using the full frame. So to me shooting un-cropped is better (unless you really need the buffer room) as your are more likely to get a better framed shot after cropping in PP.

If you're shooting using the full DX sensor, what do you see outside the sensor/viewfinder? Nothing. That can make it difficult to time action shots prior to their entering your viewfinder/sensor.

Shooting in 1.3x crop, you have the remaining DX viewfinder, outside the crop viewfinder (see Mako's Sharpie) that is still visible to you unlike the full DX viewfinder in DX mode. So you can see what is about to enter your viewfinder using 1.3x crop that would be completely occluded using the DX viewfinder just prior to entering.

You are not getting my point. Using the same lens at the same FL from the same distance you are not gaining anything by seeing what is about to enter the frame of the in crop mode because the image in the viewfinder is exactly the same.

The crop mode is used because you subject is further away and the lens you are using can't fill the frame with it so whether you take it in crop mode or DX mode you are not really gaining any extra "view" outside of the picture you are taking because if you subject is small enough to fit in the crop mode frame then you would be cropping it in DX mode in PP anyway (or maybe not if you prefer the composition of the shot, but that is where DX mode gives you more flexibility).

Sure if you are close to your moving subject in DX mode and it fills the frame it's can be get it hrad to frame it properly and you could move further away or zoom back to frame it easier but then using DX or crop mode would still make no difference.

The only thing that the crop mode gives you references easier framing is if you wanted to get the subject in the center of the frame when you take the shot - you might not be able to do it as easy in DX mode but that doesn't matter because the frame is larger! So you can crop it PP to exactly the same image as if you were using crop mode!
