In random bits of news around the globe, X-Fire have launched a special section on their website for international/overseas customers. They are still updating things, so some Japanese words may remain on the pages but they are getting there and accepting orders in English.
Western Arms now have the SCW / SV Infinity 4.3 Expert in stock on their site, which should mean that’ll hit the retail shops pretty soon. It’s hard to keep track of their releases from day to day as they all look the same to me these days. Price on the new small SV is 24,800Yen.
