We all know that NSS 6 already completed its life last year DEC and there were news that it will be replaced my new sat SES-12. What I think is that Dishtv has initially started to implement this strategy of shifting the channels from NSS 6 to other sat since NSS 6 will no longer be there. As of now they choose SES-8 and shifting the channels to it.
Maybe in near future they might be shifting channels from SES-8 back to new sat SES-12.
Would be thankful to Dishtv if they uses new sat SES-12 for all channels since this sat has good footprint in Middle east region as well and people there can get all channels which they are currently missing.
