So what if Trump wins in 2020? Will, that means the game is delayed until 2025? If so that would be a 12 year gap between 5 and 6. That's nuts. That could be ammo against Trump for the 2020 elections. Democrats can be like "If Trump wins you won't get GTA VI until 2025! Vote for me to get the game earlier!"
Sounds like a good campaign idea.
