All evidence thus far seems to point to mistlands being just like most any other biome of the game. I think it may be prudent to ground your expectations accordingly and be pleasantly surprised otherwise if it turned out to be as grandiose as you wish it to be. I just don't see devs making such a dramatic contrast to what is already the way things have been thus far.
