You won't see traditional manual trans disappearing anytime soon, as the cost for producing them is very low.
More importantly the cost for repairing them is WAY lower.
Unfortunately the demand for them is also low.
Everytime I walk through some parking lot I look to see if the 'Vette, Mustang, or whatever performance car I'm passing is a manual or not.
90% of the time I'm sadly dissapointed
