Not sure. It depends on if my physical copies of Demon's Souls and Sackboy: A Big Adventure arrive on time. I'm getting Miles Morales digitally, so that's going to take a while to download after I get the system started up (the first thing I'm gonna do is get that thing downloading, since it's a big download).
Probably Astro's Playroom, just to see how the Dual Sense feels with a game that will no doubt be utilizing some of its features, and then some PS4 games I also have that I've been sitting on.
But if I get Demon's Souls on time, that one for sure.
