Depends upon which siege we are talking about. If the 17th Century battle is the one you are referring to, then LG is certainly right on that. With regards to the 1529 one, they probably establish a vassal within Austria until getting kicked out soon after due to overextension. Protestants will be stronger inside the HRE, and Spain will remain a major power for a lot longer.
