A selling point which isn't enough in the current climate when it comes to living room hardware. As of June this year the Wii U has only sold (to retail, which doesn't actually mean total sales to consumers) 13.02 million units worldwide. [0] Compare that to the either Playstation 4 or Xbox One sales and the pricing of their new 4K iterations (respectively PS4 Pro and Scorpio) and it's obvious to see both enthusiasts and the typical consumer no longer value Nintendo's games enough to shell out $300 for their small catalog.

Their current strategy consists of developing and selling software to the casual cohort they lost between the Wii and WiiU release, in order to bolster new hardware sales. Buying their stock on the announcement of that software is ill-advised because no one knows what their new hardware looks like and whether or not they can convince that audience to spend cash on it when the alternatives are such better/easier sells.
