(Zoomed Pictures Of Gameplay Screens)
As you can see, the mini map is the only thing on the hud at all times, unless you have wanted stars and or your switching your weapon (i think they confirmed that when you switch your weapon it will just show an icon of it then just go away), And the health meter is on the left side of the mini map, so im guessing the right side would be where the armor bar is.
Also take note that the mini map has no color and it is semi transparent, and its easier to see the roads than on past GTA's
*EDIT* Whole article seems to be up now i think!
