Hi Srikanth,
//Why only Hindi and Marathi?
Why not Tamil, Telugu, Bengali and Sanskrit?//
What Asaf meant to say was that they are trying their best to invite the right people from communities who didn't make official community nominations. Marathi and Hindi were given only as examples by him. I am sure WMF will invite people from all across the Indian communities. He has already assured to look into the English Wikipedia community in India.
Asaf has already made clear that he will honour all official community nominations.
