Who said .co.in and .in will be coms and infos?...
They are just a country's official extension but this country happens to be India with 1 billion people (a large market), a well educated and young workforce specialized in the I.T. sector, speaking English etc. etc.
This is all about and not what extension will surpass .coms! If you can't see any value in .co.in and .in then go ahead and buy useless .coms that no one wants to buy cause the really good ones have been regged ages ago. But on the other hand you can find diamonds ending in .co.in and .in
And wot... The best one from your list is audiovideo.co.in :tu: Nice catch!
