That's just Sanwa's website that's been around for years. According to their distributor list, it looks like Serpent USA is the new USA distributor. Which makes sense, since Sanwa has no interest in aircraft radios and are only focusing on car stuff.
According to Sanwa's website, as of April 1st, Serpent USA has taken over sales and support. Global will continue to support customers as long as they have parts available. I'm sure they'll be more information regarding this as the transition continues.
