I preregistered loads with the official registrar so I have more chance of getting them

I hope you realise how much they cost...are you tied into getting them? Because they aren't your average $6 domain!

As for their worth..that's hard to tell as they haven't been released yet. India is a developing country though and i think the top level domains (one word, dictionary such as sex.in) will be worth alot of money.

Good luck getting them....will be very hard!
