I get that Rockstar probably feel like this game is too big for a few minutes to do it justice and they probably don't even know what to show off. But I hope they still end up doing a gameplay trailer, even if it doesn't have a voiceover and is more in the style of the leaks where the player is just doing and experiencing random things in the world. Could even do a cheeky reference to the leaks by having the player shoot a R surrounded by a square into a wall
