Well, they talked quite a lot about SMTxFE at E3, gave the vague 2016 date, the original trailer was also on the Future Releases list and is not there anymore; neither the newest videos.
But Nintendo likes to update the Wii U eShop randomly. I swear the main page looks different every week, outside the obvious new games, is like they add and change things around too.
EDIT:
New page, so for those joining now...
The 'Future Releases' list seems to display whatever videos Nintendo wants; currently some E3 2015 videos. No relation to a game release per se.
