Unless they are planning to integrate all of the SonyLIV library (including LIVE TV & Sports) into ZEE5 anytime soon, I find 1499 to be quite a jump from 699.
Does ZEE5 alone have a library enough to make such a leap?
After the recent update of app in Android TV it's maybe the endpoint of sonyliv and merges with zee5 very soon..even the new 4k plan of zee5 maybe the 1st step towards the changes..
