They actually address the problem in the blog post:
>Once completed, V2 will become the primary world generator, and you will enter the new world of Orbis. V1 will eventually stop generating chunks, but your old V1 worlds will still be accessible.
So I had my mind set on something closer to the way Minecraft worldgen updates work, but it seems very likely no world reset will be needed when this does come out anyway.
