Do you think GTA VI on Xbox and PS5 will have frame drops around 20-25 FPS like GTA IV on PS3?

RDR2 runs at 30FPS with the PS4Pro version on PS5. I never played RDR2 on a base PS4 but the PS4 Pro frame looks like a solid 30fps. You think GTA VI will look like RDR2 or frame rate will drop around 20 FPS?
