I don't see the problem in keeping hope for Ridley...especially when we take a look at the representation of each of the main eight franchises. Let me explain:
Super Mario Bros: The heroes, the damsel in distress, Gaming's most famous villain, and a Cosmic Deity
Legend of Zelda: The three parts of the Triforce, some with multiple versions
Kirby: The main three characters of the franchise
Starfox: The main hero, the partner, and the rival, solid representation
Kid Icarus: Has the hero, and will most likely have the Goddess of Light
Donkey Kong: Has the main heroes, will most likely also have the main villain
Pokemon: Speculated to have five of the world's most famous and popular pokemon...and Jigglypuff
Metroid: TWO SAMUS'! ...................What?
