Yeah we saw this on PS4. Most of them will be indies/cross gen/remasters, and all of a sudden indies/cross gen/remasters will be cool again.
Though with this being an amazon listing, my bet is mostly cross gen games. Games that were always coming to the PS4, but now they will have a PS5 version. Then subtract a few possible special editions and add in the late remastered ports, and all falls in line with how the X1 and PS4 started.
Most of the probably cross gen and special edition or season pass and also accessories.
