Bangalore will always be Bangalore to me. I grew up in that city.I think the name has to remain as Bangalore as it reflects the cosmopolitan image of the city . It is one of the most recognized cities in the world ( I live abroad so I know that foreigners recognize it). I think it would be a mistake to rename the cities. For the Kannadigas who speak Kannada it will always be Bengaluru. If it is indeed named Bengaluru non Kannadigas will get the pronunciation so wrong and they will butcher it. Let the name Bangalore stand and Kannadigas can be proud of their Bengaluru.
