50m. They will release physical disc in 2027 and people will double dip

Physical disc is reportedly happening December. Code-in-box is just launch copies according to this. This is from same person who said GTA 6 wouldn't have physical release day one, which turned out correct.

I don't think many people would spend $80 on a digital copy and then buy it again on disc. What's the point?
