Is it time to upgrade my D7100

[PatrickW]

Thanks everyone. Looks like I am going to stick with my D7100. There have been improvements, but not enough to justify upgrading just yet. Think I will buy more glass instead.
BTW, I listed the 300 F/4 as a lens I use, but I never use it for night games. I probably should have left that off the list for this discussion.

If you care for night games, D600/610 is a remedy for all lenses you've got.

AFS-300/4D is a good lens with fast focus speed. Here's some photos of night games taken with D300. For your reference, D600/610's ISO performance is 2-3 f stops better than my D300!
