We know we're getting old areas and someof us are wondering which will return, but has anyone considered which won't return? Personally, I think that it is very unlikely for the polar field to return since the return of the snowy mountains means that the peak is likely to return as well.

It is also impossible for the old desert to return because the dunes are announced, and most of the other 1st gen areas are unlikely to retern as well. Anyone else rule out a few possibilities?
