I think Zee might be negotiating addition of all recent HD channels(Zee Tamil HD, Zee Telugu HD, Zee Cinemalu HD and Zee Kannada HD) as a bouquet with DTH operators rather than individual channels.
But they are not adding HD Channels in SD TPs and since they created 2 HD space in 11641 TP they will add some HD Channels in it at the earliest.
And also Airtel doesn't give much importance to regional movie channels & K TV HD is the example.So if there is a launch this week Zee Tamil HD is the top most priority since its been continously demanded for past 3 months and for the next slot Zee Telugu HD is the natural choice but if deal doesn't go through there are plenty of HD Channels already pending.
So to say they are planning for Zee Telugu & Zee Cinemalu HDs alone doesn't make much sense.
