For me personally, I would love to see the Resistance series get some love. A collection with all the titles, including PSP, added together with upgraded graphics would be nice but I would really love to see a new entry into the series.
It’s that or Legend of Dragoon but that’s a real long shot.
Sly Cooper would be fantastic on modern hardware. Thieves in Time is a lot better when emulated because it fixes the game’s most glaring flaw compared to the PS2 games: load times. I can only imagine a Sly game designed to be run off an NVMe drive with modern graphical capabilities. I wonder how its art style would be adapted to higher fidelity.
