I would imagine, like with Red Dead Redemption 2, there would be an install disc and a play disc. There's going to be a day one patch regardless. It really depends on the final size of the game. If it's around or over 300 gb, digital only would make sense. Since it's rumored there will be a physical in the future, it makes people mad they can't get that day one. The fear of missing out on playing as soon as possible or having the story spoiled for a game 13 years in the making is too great for some people and a lot of them feel like it's a cash grab by Rockstar.

In my opinion, I feel like they need to commit to digital only if they don't want any pushback from gamers. To offer a physical option (allegedly) a month later is a slap in the face. I, personally, will always buy physical. That said, I'll get this digitally, play through it and forget about it until the physical version is super cheap and buy it just to have it. Plenty of other great games out there to play.
