Cyberpunk, though the timing of that purchase will be determined on how performance is on next gen consoles right at its release date. If I think it looks and runs decently in just 'boost mode,' I'll buy it in November; if not, I'll wait until 2021 when the promised next gen version is available.
I'm getting DMC5SE at launch, though. I loved DMC5 and as ever, want to see what playing as Vergil is like with the SE release. I hope there's a few more unannounced surprises, too!
EDIT: Yakuza 7 will be an auto-get depending on when I get my Series X, too. I know the Series X optimized edition is a timed exclusive, so if I get my Series X before that exclusivity ends and presumably a PS5 version releases, I'll buy it for Xbox. PS5 if I don't have an Xbox by then.
