Bro, you can expect it by 15th September, 2016 !! In my earlier post, by mistake I had typed 11th September but actually its 15th September, however I have edited that post also now !!

Its just a simple calculative analysis guys !! You can see that SPN has launched SAB HD after 14 days of actual testing, Similarly you can calculate that Sony BBC Earth HD will also be launched after 14 days of actual testing i.e. since when testing was started with the actual programme video of the channel along with the logo of the channel and also along with the DD sound, and these all started together only since 1st September, so counting from 1st September I think, it will be launched on 15th September, just after 14 days of actual testing !! And looking at the current speed of SPN, I think, it will be definitely launched on 15th September !!
