Nobody, but it's the most logical. For example, the 3ds will be dead in 2023. Nintendo closed the e-shop for 3ds, and won't give updates for it anymore. Other games (like pokemon if it's controlled by game freak or pokemon company alone) can still keep their games up, while the 3ds is already dead. That's not what nintendo wants, because than they can keep it up forever. This is not sure, I searched till the end of internet to find an answer on this question, and i couldn't find one. So this is MY opinion.
