everyone has been guessing but i dont think that irongate has ever said.

People are saying hearth and home will be fine with old worlds and that once they add new biomes, all the mistland you have explored now in your world, won't fill out. Any that you havent explored in your world yet, will.

I plan to start a new world anyways. Waiting until sep 16 to start playing again
