Yes indeed folks, as mentioned at Famitsu recently, the Shining Tears Opening Theme will be available to buy as a CD single in Japan from November 26th onwards, priced at 1,134yen (around US$10).
No picture is available at this time, however the Sega Direct product page for the item also says that the Ending Theme is on the CD – so you had best make sure you have completed the game before listening to it 😉
