Just curious. I have trouble seeing the D7000 LCD when it is sunny. I know the D7100 LCD is larger and has more resolution, but why do you think it will have better visibility when it is sunny? If it is that would be a big help.
I also have some difficulty with the viewfinder text in the D7000. Since the D7100 will have an OLED display for this I think that will be a big useability improvement.
