Come May, the Japanese version of Sonic & All-Stars Racing Transformed will be released, and if you happen to live in Japan and pre-order, you get a sound track CD.
However, a recent listing posted on HMV.jp would indicate that the OST is to also get a full retail release. In fact several Japanese retailers have recently posted a listing for an ASRT soundtrack on their websites. Details are that it’ll be a single disk release, and its due out on May 14th.
Despite a strong demand for a physical soundtrack release since the games début here in the west, there doesn’t appear to be any plans to bring this over to the US or Europe at this time, which isn’t unusual for Sonic OST releases. But if that changes we’ll be sure to let you know.
