Should I buy a PS5 Pro for GTA 6?

I’m debating if I should pick up a PS5 Pro before GTA 6 comes out, however…
I already have an Xbox Series X and a solid PC, so I’m not really missing anything right now. But with GTA 6 launching on console first and no confirmed PC release at launch, I’ve been going back and forth on whether it’s worth buying a PS5 Pro for the “PS5 Pro Enhanced” version.
The other thing making this decision difficult is GTA Online. If there ends up being no crossplay between Xbox and PlayStation, I’d honestly rather be on PlayStation since a lot of my friends have switched over from Xbox in recent years.
