That's right, VIZ Media now holds the exclusive American product licensing rights to Hatsune Miku in North America - meaning VIZ, and only VIZ, gets to sell Miku-related items in the States.
This won't mean much right now as the Vocaloid software has yet to be sold to the States (though an English version of Miku will be coming to the U.S.), but VIZ does plan on showing Miku off during the 2011 Licensing International Expo, which will take place in Las Vegas from June 14 to June 16. VIZ plans to use the Expo to find potential partners that would help the company sell Miku products.
