The catch is: code in a box only (if sold physically) as it’s not being sold as a disc nor cartridge. Vote with your wallet, is it worth funding Rockstar knowing they won’t ever release this as a physical game (digital only title)? Is the Ultimate Edition (in game stores are locked under a real pay-wall) a rip off if you’ve pre-ordered it being aware of what it offers in return of taking your money?
It’s definitely going to be a commercial success (already is from pre-orders), and even if the gameplay is mid af, it’s going to be glazed by every major review source.
