In 10-30 years
Somalia will not exist anymore
destroyed from within. Each of the main clans will have their own territories and isolate themselves from other. Every territory will have its own flag, currency, government, military and so on. 
30-100 years
With the riches in natural resources and ever expanding need for resources by the powers of the world at this time, the Somali lands are seen as a strategic location, much like the Gulf region is today. Somalis by now have their own clan states not really united except through trade and policies. Seeing this division the powers of the world decide to turn each of the states against each other. Arming the minorities and funding rebellious guerilla groups and their tactics. Somalis go to war once again but this time its for control of shared resources and who and what state should benefit the most.
100-200 years
After a long and hard fought war Somalis have bitter resentment for each other and of each others states. No more communication, trade, and policies that are united to help the region. Instead Somalis are beginning to split apart with clans becoming more or less the identity to the people. Language begins to change as well, Somalis in different states wont understand a word of what others are saying. Cultures as well change with certain states being more free and open minded and others are more strict and conservative.
200-500 years
This is where things begin to fuck up. Somalis are a thing of the past by now each states has its own Identity. New ethnicities are being formed and certain states will look different to others. A muscular tall lightly coloured state, the thinly brown skinned complexion of the other states and the most detested are the pitch dark, dimwitted, short and rather unattractive failing state. Now the Horn of Africa region is basically a collection of multiple states with its own abstracted identities and no one really cares about past people and perceptions, loyalty is to your state.
