'Horizon' upgrade mess seals the deal: PlayStation 5 title upgrades will be $10

Washington Post - Technology News 

These various upgrades raise the question: Just how valuable are the lines of codes that distinguish a PS4 or PS5 version of otherwise the exact same content? It's not a question customers should be expected to answer, especially this early in the console generation. For now, Sony has an answer: That'll be $10. The remaining questions include how developers will now address that $10 value attached to upgrading to a PS5 version, and whether that consistency and price is reasonable enough to keep players of both PS4 and PS5 happy.
