According to this article from December, 2018, Denver now has new naked scanners. The upgrade is that it's faster (and possible has fewer false positives):
"The new machines can transmit and receive information almost instantly, because they’re multistatic, rather than multi-monostatic systems, Rappaport said. So, people only need to stay still for one second, not three."
At that time, Denver airport had the new machine, but the are plans to continue rolling them out. TSA continues to find ways to spend money!
