I'm here to bet NO, as gta6 is a highly expected title, and gta5 is the third best selling game, it makes sense to expect high numbers.

@ThaNook That’s a lot of ifs. IF GTA6 doesn’t get delayed enough that there’s not enough time for people to buy, IF it’s actually good, IF it doubles the sales of 5, and IF Minecraft doesn’t sell many more copies of the games then there’s a chance it becomes the top selling game.
