The SWOT analysis of forming a new state of Telangana shows the following :
Strength : fulfillment of regional aspiration.
Weakness : Coping up to have a new fourth capital after Chennai,Kurnool and Hyderabad for Andhra Pradesh will not be easy.
Opportunity : growth of a new glittering capital for Andhra Pradesh, bringing about development and facilitating people's participation in the Telangana region.
Threat : devaluation of the brand of Hyderabad, lowering of the prices of real estate there, proliferation of secessionist movements across the country, dispute over resources like water and coal and the consequent Law and Order problems.
With already having 9 Hindi speaking states, we can certainly have two Telugu speaking as well, but given the above analysis we need more concrete reasons to form a separate state of Telangana.
