Schumi won't retire - his still in his thirties and he's not too old to be that competitive. Juan Miguel Fangio was still in competitive car racing when he was already in his early-to-mid 40's.

I agree with the analyisis of M2: Alonzo is in a three-year winning groove because Renault has a more competent vehicle package for three years in a row. It would be interesting to see Schumi, Alonso and Kimi duke it out on one single type of F1 vehicle - say a Jordan.
