Name of preview video song confirmed
According to my sources, the theme song we hear in the video that premiered at Tokyo Game Show 2009 earlier this fall is entitled "Living Universe".
I don't know the singer or songwriter yet, but I DO know there will be a special CD single given out to people who pre-ordered the game in Japan via either Amazon.co.jp or the online Sega Store.
Both sites offer different label art on the actual CD itself, but the contents are the same: three tracks, one of them which is confirmed to be"Living Universe".
