My "team", including my wife and a very few close friends plan on a map wipe (restart the game fresh) once Hearth & Home is out, even if it is possible to continue using the one we are on. We just finished the Moder boss, and we plan to gear up and savor Boss #5. Hopefully Hearth & Home will release after we "win" the game. If not... we *might* start with a fresh map anyway and play until then.

The great thing about a map wipe is that you get to take what you learned from the prior map and see how well you can hit the same goals, or even new goals on the next one.
