Players all over the world (normal players, RNG abusers and hackers alike) will rage over the fact that their Pokémon from the previous games will all go to waste.
I wouldn't be surprised if many players quit playing Pokémon altogether in such a scenario... I know I would seriously consider doing so.
Trollfreak will be shooting itself in the foot if it does that.
This. As much as I love the series, I would consider leaving the series entirely if I can't transfer (or at least staying within Gens IV and V). --- I'm not easily impressed; I'm usually oblivious to whatever's in front of me.
