These guys have had Piaggio in the form of Piaggio and Vespa scooters for a long time. They have had a lot of time to think about taking on Moto Guzzi, but haven't made a move on it for at least a couple of decades. No mention of the change on their website, though.
Interestingly, the MG USA website shows the Las Vegas arm of the company as a dealer now, but not the Reno location...
