That's pretty much what I think this will do as well - I don't think the physical areas will change, but the nature of stedding will vanish, with the Ogier, leaving behind forests with giant trees and none of the other characteristics that made those areas stedding. This means a very great deal of the Seanchan Ogier will no doubt translate as well - all those who live in their stedding and aren't on duty as Gardeners when the Translation happens.

I'm fairly undecided whether the Translation will happen only after TG, or if all Loial manages to do is to convince a large group of Ogier to remain behind and fight, because if TG is lost, the Ogier "homeworld" will be destroyed just like the rest, while the rest of the Ogier Translate before the LB.
