I never said they weren't? It looks like they are going on a rotation system. TTC was 2013, TLH was 2014 and TToF was this year. My greatest guess is that they will make the BoTL this next year whenever The Hidden Oracle comes out because that's the day the other books came out (along other books). They are clearly still making the books because a GN was released this year.
