I'm not so sure about Luna pricing. It will have a cable model: a basic subscription then each publisher channel will have a sub cost on its own above that in order to acces its games.

For example, in order to acess ubisoft games, channel, you must pay extra sub on top the basic sub.
Also the 5,99 bucks basic sub will only work during the early access.
