I’ve been dying to listen to the new soundtrack for a while and after what I heard during one of the panels at pax I can’t wait to get my hands on it. I don’t really see any reason why they would hold on to it until after the game is released, I don’t think it could possibly hurt sales at all because anyone that would want to buy the soundtrack has probably already made up their mind to buy it.
At the very most I’d really like to know what the official OST release date is, it would also be pretty awesome if we were able to listen to a higher quality version of the song that played during the pax panel.
