Out of interest sake, (since it's not something covered very often on the board), what might the repercussions be of Lajos II of Hungary leaving behind a legitimate, posthumous son (call him Istvan, for all intents and purposes) by his Austrian archduchess wife? Would the Hungarians agree to elect an infant in arms 'king' or will they still side with Ferdinand? Or Sigismund of Poland? Or the first guy who shows up with an army and persuades them to elect him king?
