Hi there. Newbie here. I've been playing GTSport for a year now with the disc that came with the console and I have reached level 45 but now I'd like to buy the digital version to save swapping discs all the time. I understand that I would have to uninstall the disc version before I can download the digital version but my concern is over my game progress. Some people say that it will retain the progress and some say it won't. If it doesn't keep my progress then it's not worth the purchase. Does anyone know for certain what will happen?
