Vanilla map reset at 1.6

I've been thinking about doing a map reset for a while now, I'm just not sure when a good time would be, until now. Halzyon and I were discussing it and 1.6 might be a good time to reset the map due to some biome updates, though I'm not entirely sure if that's at 1.6 or later. A map reset could revitalize the server and get some activity going and give us a nice time to push for more advertising.

What are all of your thoughts on this? I would put the map we are on now on the website for everyone to download and check out if they so wished.
