That looks pretty good to me. what lens did you use on that shot? (and 900 ISO )
It's my 200-400 f/4 with a 1.7x teleconverter on it.
Auto-ISO, hence the weird value. That's something else I like: the "auto" minimum shutter speed for auto-ISO that adjusts the minimum shutter speed to account for focal length, with a weighting that you can adjust. Mine is weighted one tick slower than "normal" which seems to put the shutter speed right around the 1/FL rule for the physical focal length of the lens. "Normal" seems to take the crop factor into account and adjusts the shutter speed for the 1/FL 35mm equivalent. This isn't new to the D7100, but it's new to me.

and, what crop mode?
Let's see some really high ISO pictures and tell us how well the AF works in the dark.
I should have put it into the crop mode but I didn't. That image is fairly heavily cropped.
No good high ISO photos from this morning, but I did a lot of autofocus testing and it is a whole lot better than the D300 for low light. By which I mean, I tested in many scenarios where the D300 would simply not find focus - very dark shadow areas in the trees before the sun came up - and the D7100 focused every time. I'm really, really pleased with the performance improvement.
edit: Okay, here's a lousy ISO3200 photo from this morning, since you asked. The little guy wouldn't come out of hiding so I just snapped this when he poked his head out - it was before the sun had gotten over the trees. Dark exposure, very heavy crop, straight out of the camera... this is pretty much a worst-case scenario.
Not a great example, but the OOF areas are a lot less noisy - and a lot finer grain to the noise - than my D300 typically is.
