I don't know when they will release the hybrid collectibles, but E3 is around the corner. Maybe they should release a new TBT direct by then like they did in the past three Junes.
I would also like to know why they refuse to reintroduce weird dolls. Even collectibles like Pokeballs, party poppers, and pinwheels (which are highly unlikey to return) would have a second chance, but weird dolls will never have a second chance.
