WI: Vienna falls?

What would the consequences be, if the Ottomans had won the Siege of Vienna, in 1529? Let's assume a POD, where the Ottoman army manages to smash the arquebusiers during the final assault, for the sake of this scenario.

What happens next? Would there be internal unrest in the Holy Roman Empire? And how would the other major European powers react?
 
François Ier is going to gain some conceding from Habsburgs on Italy, would it be only temporary, if these wants to prevent a two-front situation with a Franco-Ottoman cooperation being even more justified by events.

Treaty of Cambrai would probably be put in the dustbin of History or at least being renegociated.

Now, I don't think that Ottomans could hold on Vienna. Swallowing up all of Hungary and Croatia is doable, but they already went by their maximum logistical reach with Austria, from one hand, and had little immediate ressources.
They had no baggage, and sustaining in winter a large army would have been too difficult critically in face of a strong counter-attack.
 
I wonder if this would help or hinder the reformation. On the one hand, the strength and the prestige of the Emperor have just been dealt a major blow which might make suppressing protestants in the Habsburg Crown-lands more difficult. On the other, a weaker Emperor may mean that some of the Princes who converted as a way of securing greater independence from the Imperial Crown might find political rather than weaker ways of doing so.
 
It's going to be a bit weird.
Most certianly reformation would be blostered there, and protestant princes seeing there a material justification of the rightfulness of their beliefs : I think you could see a more widesread reformations movement in a first time.

That said, the unavoidable Habsburg counter-attack (which have big odds to be partially victorious : I'm not calling a full reconquest, but taking back Vienna) and the pontifical support on Habsburgs (IOTL, papacy decided that before the imperial hegemonic danger, they just withdraw military support against Protestants, something that is not going to happen that soon with a bigger Ottoman threat), you'd have some backleash.

I'd say, but that's debatable, you'd have a more important Reformation widespeard, but a stronger Imperial reaction afterwhile.
