From what has been shown already on the #sneakpeek gameplay previews, the game will play out in a 3rd person POV.
Most likely making 1st person pov available for players to choose from will help expand the reach of the game and fit everyone's preferences.
The need for 3rd and 1st person POV exclusive servers is meant to deny any advantage from peeking while playing a 3rd person against an exclusively 1st person pov player.
