Star Wars: Jedi Survivor, the PS5-XBSX "exclusive" is also getting ported to the PS4-XB1.
This cross gen period is going to go on forever. It also tells you how far those engines can scale.
And yes, it's fairly obvious but generational leaps aren't what they used to be. N64 to Dreamcast (a period gap of really only 2 1/2-3 years) was a bigger jump than what we are seeing from PS4 to PS5.
