Either the full item should be available, or maybe an in-app purchase. I know that the Sentinals of the Multiverse tablet game has been released and it is looking at how to release new decks.
Either way, I am hoping that Obsidian releases it soon...even if it is just maybe with 4-5 of the iconic characters and the first one or two scenarios. That way people can get interested in it and hopefully keep it going.
