oblivion - will there be a generate button?

Hi!

As many others i am already waiting for the release. A friend of mine made a site for it: http://oblivion.melian.cc


But that's not why i started the post. I was thinking while looking at the screenshots, that the trees and nature are completely generated by the computer. So when i start the game it will generate my version of oblivion. But will it remember it or will it generate it new every time i enter the game or dungeon or.. i don't know, like diablo 2 the map.

I thought of running through the forest in circles becouse everything is generated over and over again and you have no point of reference (except of a map) where you have to go..

Playing Gothic 2 we started to memorize which plants we find on which sites.. like a specific tree... now what? The tree is there but the plant not... the tree and the plant are moved 50 meters to the west.. the plant is there but the tree not..
That's a new way of playing scottland yard.

The other way would be that the forest is generated only one time after creating a new character, specific to the hardware you have installed. But then, what if you change it to a better one, will you still see the old version. Will there be a generate button to recreate the forest?

Let the question enter yourself and think of it as activity for the break until the game is in your hands.
