Star sports tamil sd and hd , sony tamil gec, star vijay hd are few more tamil regional channels lined up for launch.. source- mib permitted channels still jan 2016
I think airtel add the star sports regional channels at the launching. So good channels should be delayed in adtv.star and adtv is in good relation,so Airtel give more priority to star sports channels. I also think these channels are almost launching before t-20 world cup.
