It's been half a year since HTC's impressive upgrade to the Butterfly hit shelves, and in all that time it hasn't received a significant update. But if a report from well-known HTC insider LlabTooFeR is correct, the Butterfly S is in the process of being upgraded to Android 4.3 right now. It's also getting the slightly newer Sense 5.5, as seen on the HTC One Max, and decidedly not seen on updated versions of 4.3 for the original One in the United States.
