According to PlayStation's official blog, "... Journey has officially broken PlayStation Network and PlayStation Store sales records, surpassing all first and third-party games to become the fastest-selling game ever released in the SCEA region on the PlayStation Network."
This bit of heartening news was accompanied by news that the soundtrack, composed by Austin Wintory, will be released to the delight of Journey's fans on the PlayStation Store and iTunes on 2012 April 10. A limited CD release has been hinted at as well.
Very cool Journey rocks it deserves it.
