The satellite has faced many problem before its launch, don't know what will happen after its launch. :u Hope no more delay and everything goes well, then the launch will be in 29th.
This is not fault of tata sky. Now only we have to wait for launch. If mission goes to fail then tata sky will be move to other satellite [isro will lease foreign satellite and shift at 83 E] so dont worry. Tata sky will add channels in any way in new year. Now only we have to wait for finish the launch mission of gsat 10. Tata sky will not affected weather it successfull or fail like airtel.
