Nintendo has been doing really well the past year due to the success of the Nintendo Switch as well as their mobile games. Fire Emblem Heroes has done very well as a mobile game with in app purchases, and it doesn't seem that Nintendo is going to be abandoning the mobile platforms anytime soon. Yesterday Nintendo announced that a Mario Kart game is coming mobile next year, and if done right, that could be huge. I'm incredibly excited for this, I just wish I didn't have to wait so long to get my hands on it.
