WPCentral reports that a reader sent in this picture of what appears to be a signal testing rig for the HTC 8X. Interestingly the devices do not sport any obvious branding, making it impossible to know if it is AT&T, T-Mobile or Verizon doing the testing, with all three carriers expected to carry at least one HTC Windows Phone 8 handset.
Commenters in the thread note that it is strange that no information besides the single picture showed up, suggesting to me that this may be a controlled leak, possibly by Microsoft, just to make sure we know Windows Phone 8 handsets are indeed on track.
