Indian nationalists (Hindutva) have arrived at different numbers

This was my impression too. As I noted in a thread some forums up, the current (politically?) popular theory in Indian history is that the Indus Valley Civilisation gave rise to the Indo-European language group, and there was no invasion of the Aryas, but an evolution of their society.

I find it hard to swallow, but would like to see the evidence.
