It stems mainly from the fact that Nintendo makes cartoony/colorful/easy to pick up and play games -- which is basically what the mobile market is dominated by -- Candy Crush, Farmville, Angry Birds, etc.
So people see mobile games making a ton of money and figure Nintendo could make a ton of money there too. Which might possibly be true, the problem for Nintendo there is it would also undermine their handheld line and touch only controls don't accomodate all of their franchises.
That and the whole Nintendo pride thing of not supporting other platforms.
