Pokémon is nothing else than a game, not only it's impossible and will be impossible for a (very) long time but even if it would be possible, it'd require a cost and it wouldn't be something useful or efficent to do.
It's more likely, given the recent improvement of holographics technology (react to touch, etc.), that future (2020 or so) Pokémon games will have a device which will display an holographich Pokémon with decent AI and that will reach to touch whose use will be to boost its happiness and some other variables (Devices that exist today minus the holographich/AI, which are inevitable if the progress will continue to advance), maybe even have holographich vs holographich pokémon battles (again, thanks to the react of touch, which already exists).
As for the games themselves, they most likely will be VR, considering Oculus rift has already made a "first step" it's very likely Nintendo will keep up with times and by 2020(+) do some sort of support for it.
And considering that japanese people are the ones progressing in holographich technology and can already do some cool stuff like actually have them react to touch, I'd say it's a pretty good guess.
