I have been waiting on the sidelines waiting for the right time to upgrade. The D300 has been a very capable camera for me and I am approaching 100,000 clicks, but its days may be numbered before a major repair.
The specs and preliminary reviews of the D7100 make it a very attractive replacement and there are a lot of improvements (addition of video, two card slots, etc.)
I want to stay with the DX format given investments in lenses.
Are there any other D300 users sitting on the fence and wondering whether we should wait for a D400 or upgrade now?
If so, I'd like to be convinced why NOT to upgrade to the D7100 now.
