More the pity they will not get what they are hoping for. Instead they will get a semblance of Punjabi: a territory ravaged by an unceasing conflict where people can't bring up their children and build their future...
Syria is/was 1-party rule.
In new system the groups who were not represented before will "organize" and appear on political scene. Kurds will also organize and join new system, but I don't expect Syria to go the way of federalism like in Iraq.
When there's election in free Syria one Sunnite party (MB) is going to get absolute majority, their pool of possible voters is around 80% of Syria's population. And unlike Iraq there's no Paul-Bremer around this time pushing through US's preferences in a transition government.
And we'll surely not let the PKK gain a foothold in Syria.
