About the only reason to go PS5 digital as if you don't have a physical PS4 collection.Most digital PS4 games should be backwards compatible with the PS5 digital model.Though,some leaks are going around that another PS5 revision is the works a hybrid model.Where you can buy one without it and that it can use with or without the disc drive that can be installed later on if need be for physical copies.Though right now it's just a rumor nothing more.
