I guess this Direct kind shows that not only is the Wii U dying, but the 3DS is on its way out as well. With the exception of Federation Force & maybe Sun/Moon (we have yet to see gameplay), most of Nintendo's 3DS games that they're publishing are either late localizations or games based on pre-existing engines to pad out the 3DS line-up this year. While it does indicate that the NX Handheld won't be out this year, it does kinda show that Nintendo was in a bit of a rush to get enough games to keep the 3DS alive until at least early 2017. Lucky for them, the third party games are picking up the slack (a number of which being late localizations, namely Bravely Second & Monster Hunter Generations).
That being said, I'm surprised that Nintendo didn't touch on Mother 3 or Style Savvy (that is, unless Rhythm Heaven Megamix is actually Cadillac & not Style Savvy 3).
