there is no planed map reset and i don't think that there will be one. if they do a map reset they will also have to do a account one which will mean people will lose there ships, gold and ex/leave. this is not so bad for all of us older players who have beaning playing since sea trials or OW but if you are new to the game and you get reset when you just get the rank to get a new ship you will be a bit pissed.
we will see in time but it is looking unlikely at this point in time.
