In a scenario (and I don't really think it much matters how, really*) in which the Ottoman Empire joins the Triple Entente, but the Central Powers win...
I presume the Hashemites revolt with German support, while the British and to a lesser extent, the French, support the Turks and ultimately the German backed Arab Revolt is victorious.
How would Germany and Austria-Hungary want to divide the former OE? What type of client states emerge?
What would be the CP equivalent to Sykes-Picot?
Just never seen it mentioned on here, and perhaps there's a reason for that, but I've never thought of it. A map would be incredibly useful too, if anyone has the will and/or interest.
*Addendum:
Maybe neutral UK? Maybe a CP America? Possibility for Italy to be firmly in the CP (or remain neutral) here? Any changes to Bulgaria?
