Map / Compass - Coop?

OK, so I'm sure everyone here has played other games, and seen the way other games do things. But this isn't about that. I'm not concerned about other games right now. What I am concerned about, is getting lost.

As far as I can tell, there's currently no map system, nor is there a means of tracking friends (group members). If there is, I missed it. Can anyone confirm if these are planned, currently implemented but not documented, or simply not considered yet? Took me 5 minutes to find my son after getting separated during a "run from the bears" moment.

Right, my son figured that one out, but it doesn't provide a very good indicator as to which direction you need to head to get "home", nor does it show you areas where you've already been. I know having a map would make the overall gameplay easier, but at the same time, it abstracts the task of mapping the world yourself manually, as I'm sure most people would do in a similar situation. I know I would - I get lost far too easily without some form of GPS or landmarks to calculate my position with. I was just wondering if these were planned features (compass system with directional indicator for tracking "home", "friends", or "waypoint"; map to show explored regions).
