Sonic Adventure games are being re-released in Japan to celebrate the 20th anniversary of the first game's arrival back in 1991. The track listing isn't the full version of the soundtrack, evidently, but the first disc will have the classics, including the "It Doesn't Matter" theme as well as "Open Your Heart." The Sonic Adventure CD is due out on May 18, with Sonic Adventure 2 following on June 22.
CDJapan will be selling both for about $27, and Amazon Japan also has preorders available. Ah, the memories -- we can almost feel that giant killer whale smashing up the pier behind us.
