I have twice now seen my new D7100 freeze. It freezes as "on", and if you turn it off or on nothing happens.
The first time I saw it I popped the battery and it was fine for a few days. I wondered if perhaps I had not waited long enough for it to turn off (it was doing its sensor clean on OFF). So I had it only do sensor clean on ON.
Last night I picked the camera up framed my shot and pushed the shutter button -- nothing. So I looked at it and turned it OFF but nothing happened. I waited for about 30sec, still nothing, so again I popped the battery.
Has anyone else seen this?
I will likely wait a few weeks to get some stats on this, then maybe drive it over to Nikon, which is a 45min drive

Shot in the dark... What does the display show? I had similar behavior when a Sigma lens was on my D200 (rare, but it would happen). Total freeze. After I cleaned the contacts on the lens, no problems ever again. Make sure the lens is seated properly, and that it's not set to MF, with the camera set to fire only when focus is achieved.
I also have a new D7100 and am experiencing similar problems. I'll be shooting when all of a sudden the camera will completely freeze up. Nothing fixes the problem except removing and reinserting the battery. The occurrence appears random and unrelated to SD speed or the buffer playing catch-up. I've owned many Nikons, including the D7000, and don't remember this every happening.
I will try a firmware update to see if this fixes the problem. If not, it's off to Nikon for repair.
Did Nikon resolve the issue? I once had the same problem with my Nikon D200. It turned out to be the incompatibility of my Sigma 24-70 f/2.8 lens with the Nikon autofocus electronics. After I started using only Nikon lenses on the D200, the problem never again surfaced. Now with my D7100, I only use Nikon lenses.
Mark Ko posted the same problem on the D7100 Facebook group and just got his camera back from Nikon and the switch was bad and they replaced it. I'd take it in right away since the warranty is only one year so the sooner the better.
