Tata sky plus hd or airtel hd dvr ?

[golu14]

While researching, i found Tata Sky plus hd to be a lot better than airtel hd dvr except the fact that airtel has much more hd content than tata sky(at much higher price that is)But ive heard after launch of some sattelite tata sky will be able to offer more hd channels, is it true? When to expect this?And tata sky does not offer the channel Zee Action too, which i watch quite a lot, any chances of this channel being added in the future?(i know that it used to be available previously)
