With over 30 million downloads so far, it goes without saying a port on PC would go far. After all, the success of the DeNA & Creatures-made mobile game so far has just been due to its release on Android and iOS platforms.
With the massive player base on platforms like Steam, there's no telling how much extra money the digital card game could make.
While this would be a great way to kick off potential next set, the franchise does not have a record for releasing games on PC.
However, the franchise is still one of the biggest IPs in the world, and the cost of development keeps going up. With that, you can never say never to Pokémon trying out new things.
There is currently no word of an official PC port for from either DeNA or Creatures Inc. That means many PC players won't get to be legitimately amazed by the game's best full art cards on their larger monitors just yet.
