Well bro what I got from my sources is If and only if HD customers at least more than 50 show interest HD it will be added. Otherwise till now only SWP HD is confirmed by December.
HBO Premium HD channels will only come if customers demand.
If all Airtel members here show interest and somehow we can send a mail to Airtel mentioning we are ready to pay for them it will come by December as well.
All who interested must tell this to Airtel as a combined mail
Honestly, mailing individually will not put any pressure on them.
