Ottomans are pretty much doomed. They will soon be expelled from the Balkans.
You are DRASTICALLY underestimating the problems here. Regardless of your belief that they are "doomed", you can't discount them. Their territories are protected by the Treaty of Berlin, a treaty signed by every single one of the European Great Powers. You think the Austrians ripping it up, handing over a highly contested piece of land to an antagonistic minor power, and basically telling the rest of Europe to get lost is a REAL fine way of collapsing the system of alliances on the continent.
They already caused a crisis when they annexed it, and only then got away with it because it was better in their hands than another power.
Against Serbia, and likely Montenegro, alone the Ottoman's will win, especially in 1908. The Serbian military reforms have not been completed and the Ottomans had only 10 years before wiped the floor with the Greeks (Granted the military was still a bit of a mess, but more than enough to handle a single Balkan state, which is why three countries who all wanted the same land had to agree to the Balkan League to take them down). The Ottomans will declare war, regardless of their strength. They have no choice, the new "revolutionary" government would simply be shamed into it. Austria will lose ALL its backing in Europe, and even if Russia is happy Serbia got Bosnia for some reason they will see it as a threat to their influence if A-H is trying to curry favor.
I'll be clear, if Austria suffers a fit of madness and unilaterally abrogates the Treaty of Berlin all hell will break lose in Europe.
