They could get away with it in Gen 2 when there wasn't a pool of 600+ Pokemon to be added to. With Gen 6 adding ~100ish new Pokemon, how many of those would realistically be the new type? 15-20 at best? So now you've got a brand new type as a main selling point for a new generation in a really old franchise, and we're looking at maybe 2-2.5% of the entire Pokedex having this new type.
Frankly I don't see them going back through the Pokedex and changing types to adapt and spread a new type more throughout the Pokedex. The logistics of the new typing concept just don't make sense to me at this point in Pokemons life.
Gen 2: 6/251 Pokemon were Dark type (2.4%), 1/6 Dark types was related to an old Pokemon, 6/251 Pokemon were Steel type (2.4%), 2/6 Steel types were retyped old Pokemon, 2/6 Steel types were related to old Pokemon.
Funny how that is...
