Never were, but the thing is it was so blatantly obvious that the lack of new Pokemon in Gen 6 is what disappointed people. For them to repeat this isn't a good sign at all, and will only upset more people.
Like they could've gone without that hideous Alolan Diglett line and given us two new Pokemon, like an evolution for Pyukumuku and Komala. It kinda feels like those two forms in particular is a giant "Why not what do we have to lose lololol".
Anything would have been better. Someone was drunk when they designed Alolan Dugtrio.
