I heard that the 7100 sensor is the exact same sensor that's in the D5200. And looking over at DXO Mark, they say that the ISO of the D5200 is basically the same as the 7000.

^ If you're gonna live and die by the DxO scores, you might want to wait then.
The D800E (sans AA filter) is a bit better than the same sensored D800 at high ISO.
I'd expect the same of the D7100 over the D5200 (if they are indeed using the same sensor)
I actually have both thread topic bodys and ISO6400 is about what I see at ISO4000 on the D7K
so that's 2/3 of a stop...a far cry from the OP's results. It's early in the game...3 days vs 2 1/2 years so
there WILL be add'l tweaking and I might find the D7100 ever better than these first glances. Just sayin'
While we're discussing your powers of observation...
you said "And looking over at DXO Mark, they say that the ISO of the D5200 is basically the same as the 7000."
On MY closer examination DxO says the D5200 is ~10% better...so how is that basically the same?! Back OT

The 18% SNR (midtones) between the D7000 and D7100 are the same but the D7100 has a 1-stop DR advantage at High ISO, which is achieved by reducing High ISO read noise in half. This translates into a 1-stop noise advantage in the deep shadows, which for some images will provide a material improvement over D7000 images.

I am a Canon user. I would like to upgrade, but here is my concern. I have found the 7D with an f/2.8 lens to be insufficient to shoot kids sports in marginally lit gyms. I almost jumped to the D7000 a few months back, thinking it would provide some improvement, but I never did.
Now I'm looking at the D7100, thinking it will be a marked improvement in terms of usable iso and getting those sort of dark gym shots, but comments like this one lead me to believe that it is almost status quo from the D7000. Is there a consensus among Nikon shooters on this who moved from 7000 to 7100? How much better is low light action performance?
I'm still thinking about jumping from Canon, but I'm really not sure if the D7100 makes sense (vs a D7000). I was hoping it would be something of a slam dunk, but I suppose not.

I shot some basketball with my D7000 last year in a poorly lit gym and the pictures turned out pretty good - mostly shooting in the 2500-3200 ISO range. My D7100 looks way better at 3200 than the D7000, and I bet I could shoot at 1600-2500 ISO in the same gym now with the D7100, with a much faster AF system to boot.
Anyway the D7100 runs you $1200 while a used D7000 runs you $600. The D7100 is such an improvement for sports with faster AF and better high ISO performance over the D7000 that I think its a no brainer - unless you are willing to go to full frame. If you really want good high ISO performance for the low light gyms then full frame is your best bet. And if you are thinking of going from Canon to Nikon anyway, well you are looking to get new glass either way.

I looked hard at a 7D before I went with a D7000. Maybe wait to see what the 7D MK II looks like before you take the plunge - would save you money on glass anyway.

Better AF and High ISO performance is based my own experience with the D7000 (14 months) and the D7100 shooting at the same places with the same lenses.
Other folks here have experienced 2/3 to 1.5 stops better performance with the D7100, depending on if they were at 1600 or 6400 ISO. Most of the published comparisons I have seen have been D7100 and D5200, D7100 and D600, or D7100 and D800E for the most part. If you have direct evidence of your own that the D7000 has better high ISO performance than the D7100 then please show it here, because personally I am not seeing it.

Has anyone noticed there's a 1-2 second delay when magnifying to near 100% on the D7100's LV when in stills mode? I have the OK button configured for medium magnification - when I press it the screen freezes for 1-2 seconds before the camera responds to any button input. I also see a slight delay when leaving magnified view. The delay also occurs when I magnify using the magnify-in button, so the behavior is not specific to the OK button. The delay doesn't occur in movie mode, however movie mode does not have the same 1:1 magnification clarify of the stills mode.
Here's a video demonstrating this. After zooming in, I'm immediately pressing the navigation pad to move the selection box, to demonstrate the lag before the camera starts responding.

I just got some Sandisk 64 mb Extreme Pro (95mbs) cards. Whoa! I've never seen the card speed make such a huge difference in buffer performance. I'm feeling a lot better about the high frame rate usability of the 7100 now. These are a must use for this camera IMHO. It's a lot quicker writing files to my MBP now as well.
p.10 #17 · The "I just got my D7100" thread - first impressions, chatter, etc.
Yeah, the card speed (I have the 32gb version) is pretty great on this camera, and I think having the speedy cards has eliminated any concerns I had about the buffer size.
snapsy, I am seeing the same behavior on my camera. Guess it's not something I care about much, but you're not alone in seeing it.

Thanks. Sadly I use LV 1:1 magnification alot when shooting so the 1-2 second is going to drive me nuts
p.10 #19 · The "I just got my D7100" thread - first impressions, chatter, etc.
The delay in LV happens after you zoom in past a certain point. I guess the camera changes its sensor scanning algorithm to increase resolution, so you can still manually focus properly. You can see how the LV display frame rate also decreases when you're zoomed in that far, so it's probably pretty processor intensive, considering the full sensor resolution it has to work with.

Got mine yesterday... First impressions are pretty awesome. I keep forgetting that this body doesn't have the lower left ok button, I got used to that on the D800, but all good. I got the WU-1a to go with it, and that is pretty cool.
and ISO6400 is about what I see at ISO4000 on the D7K
