What is happening? Japan is focusing on their respected Mangas more than the Animes, thus they're slowing down, becoming bland, or out of ideas. It's not that they're "disappearing" or "Stopping" It's that the demand is rather low.

I don't see what you mean, though. SnK (Attack on Titan) is having the Subbed version of Season 2 released sometime in 2015, and SAO got a sequel.
