All the new shows of this channel will be over in about 3 to 4 months. (max 15 episodes). It is not clear what new shows will be brought by this channel after that. Hence, There is no point in subscribing beyond 4 months.
I think the price will drop after 3 or 4 months, for the above reason and also because of need to broaden usage. Hence, Do not subscribe for any long packs..
