I hate to be the wet blanket, or the rain on the parade, but I think you gents are getting your hopes up a bit too far. My PC's were made in the USA, but IIRC a few years ago Porter Cable started making them in Mexico. I'll bet the US plant where they were built said "Porter Cable" on the building, and I bet the plant in Mexico did, too (or Black and Decker or whoever the owner of PC is now).
But I'd lay dollars to donuts that this new model PC comes from a plant in China that isn't owned by PC, and is probably the same plant that the G110 and the original UDM come/came from, and it will say "manufactured for Porter Cable", and that the design changes are simply the result of this "build to spec" manufacture.
