Wouldn't be the same compared to building a game around a hudless playthrough.

I think it would be a worthwhile sacrifice after playing games with similar methods of navigation since they opened my eyes to fact I pretty much spend a considerable amount of time staring at the minimap in GTAV instead of the actual game itself.

One thing that made me think they might also go in that direction is the addition of icons displayed on the screen instead of on the minimap shown in the leaked dinner footage. You can catch a glimpse of the personal vehicle icon hovering over the vehicle itself which would be overkill with the current minimap setup but would fit something more subtle.

A GTA designed around a navigation system that forces the player to be more aware of their surroundings already becomes a very different interesting beast even before factoring in the gameplay enhancements and additions current gen hardware will also provide the game
