The scientists in the Devon Corp building have each told of features appearing in later generations, with the exception of two, one being the Fossil reviving device because it's already implemented.
"I'm developing new kinds of Pokéballs..."
These would be the Dusk, Quick and Heal balls found in Generation IV.
"I'm trying to develop a device that visually reproduces the dreams of Pokémon..."
This is the Dream World function in Generation V, assuming it was altered to tap into the Entralink.
And the final one.
"We're developing a device for talking with Pokémon."
Does this mean this feature will be available in the RSE remakes, or in Generation VII?
