I don't think Turbine will give us the option to get player coordinates, as that would somehow make things easier for bots.
Zones? C'mon, what harm can zones do?
Rather, they would be very useful to give updated info to the player, such as where to get rep items for the zone you're in, or which task givers are closest to you, or... you know, a lot of things.
So, i approve on the GetCurrentZone!
