There seem to be too many Pokémon from RSE in BW2, and even some of the "exclusive" legendaries to RSE are now suddenly catchable (the Regis, Lati@s, etc.) But who knows, maybe they'll cater to the generation of kids like me after GSC.
Actually I think between the three Sinnoh titles you could get the vast majority of Pokemon except for the starters and most of the previous gen legends. It was not like with gen 3 where pretty much an entire generation of Pokemon was unavailable.
So HGSS probably came about more because they already remade FRLG to a large success and they wanted more filler between gen 4 and 5
