Maybe they will be added only when DTHs are ready to also add Pravah Picture HD and Star Kiran HD. Those two channels have been suffering for too long and hardly any promotions have taken place, especially for Star Kiran HD where hardly anyone knows that it exists.
Hopefully DTHs add all the four together. I have far higher hopes for Tata Play and ADTV than the others, but since Sun Direct already has Pravah Picture HD (in addition to several cable platforms in MH), it could be a dark horse.
