OoT 3D got added to the Nintendo Selects eventually.
Link's Awakening is a remake of a Game Boy game, so what has led to the 0.19m shipment is likely just that it has exhausted the pool of people who are willing to pay $60 for it. The game is going to be old enough to be a regular in future digital discounts for Nintendo software (typically 33% off), so it should be able to get within striking distance of OoT 3D eventually.
That is true, there might be plenty of people just waiting for a low pricepoint for such a game. I'd love to be proven wrong.
