I will put in better context.
Ms is doing great moves. The smart delivery is something special. Really possible because of gamepass since your librar will carry to next gen.
I don't know how Sony will react but what they expect? To sell last of us 2 again for who bought on ps4?
I always thought the next gen would have a lot upgrade patches monetized . Ms move changes that and make it easy for people to join next gen. Imagine if u can carry your library by the cost of only change the he and receiving free updates.
And there is price. Ms has the opportunity to be really aggressive with price and they can afford to be. I don't know if Sony can get on this battle and take big loses on hw.
If sony even dares to "charge" next gen patches or force a double dip ...it will be like christmas combined with easter and new years eve allong with holiday vacation in a 6 star hotel in the caribean for microsoft marketing team. They will literally tear them apart after the DRM fiasco ...they hide in shadows waiting for the right time...so NO sony isnt that stupid. (i hope).
It will surely be a stupid pr/strategic move to monetize next gen patches at least early on. Please do keep in mind concerning ps3-ps4 cross gen titles it was 10eyros to buy the upgraded version from ps3 version but imho in was justified cause it was a whole new architecture. Its not the same think with ps4-ps5 ...i EXPECT next gen patches to be free of charge.
