I've heard its symmetric, if they come out with 4mbps plan with reasonable offering, i'll go for it.
It will be worth for games.
It will get cheaper eventually,it is only a matter of time. They are most probably waiting for a pan-India roll out then they will reduce it.

At last they also know that there would be no customers with this type of pricing.
