On that grounds and speaking of intervention, are France and Britain going to just twiddle their thumbs in this major crisis? If the Danubian Corpse is collapsing, they'd inevitably want to make sure it dosent overly favor their rivals or create a massive powder keg.
Yep, once Berlin make sure his intention to dismember A-H, both Paris and London will press for a congress to divide the spoil or obtaining some concession for allowing that division.
France will desire at least the French speaking part of A-L, the UK will at least want a naval agreement with Germany, add to that some colonial bribe from Germany to both powers.
The chaos in Hungary will be a perfect time to strike Croatia-Slavonia, but South Tyrol will remain in Austria's hands,as they are protected by the Germany.
South Tyrol was/it's desired only for strategic reason, Trentino (the italian speaking part) it's the principal objective of the italian request; Rome being 'forced' to invade Croatia-Slavonia to get his claim will not bode well for the italian goverment as it was more expected that Germany will have given to her diplomatically...all this it's also know as 'I doubt Italy will remain German ally for long'
