I believe the reason Game Freak was so lazy (that's what I'm calling passing up on a really easy flavor-filled ability change) is because the Pokémon that get Immunity, save possibly Gligar, get much better abilities.
The Pokémon that get Immunity are: Snorlax, Gligar, and Zangoose. Snorlax gets Thick Fat, which is exponentially better, Gligar gets Sand Veil, which is passable, and Zangoose gets Toxic Boost, which is also exponentially better. So I doubt Game Freak will be doing much with Immunity unless a Pokémon in the 6th generation gets it with crappy alternate abilities.
Speaking of Snorlax, why does Game Freak always have to ruin our childhoods and make Snorlax's trademark, being asleep, overshadowed? I hope that Game Freak finds a way to upgrade sleep for Snorlax in 6th gen, with stuff like Sleep Orbs or an upgraded Snore.
