They will make sure the surface is fast for a WC so I expect it is only a matter of the weather cooperating- which can be an issue in Berlin at times but often (except whenever we ran there!) there is a tailwind. (There even was a tailwind in the 100m at the 1936 Olympics)

Do you mean re-surfacing the track?
