Here are my predictions, from safer predictions to more risky ones.
-Pokemon Z will be released, and it will have new mega evolutions.
-3DS/WiiU pricecut prior to the NX release.
-Final Fantasy XV will be delayed to avoid clashing with Persona 5.
-Sega/Atlus will push the Persona brand more, and for that they will release some of the PSP Persona games on the 3DS/WiiU/NX.
-The NX will be released during the final quarter of the year. Zelda U will be released on the NX as well.
-Monster Strike will release on the west, like Puzzles and Dragons.
-Miitomo is a moderated success, but the next Nintendo game will have the Mario brand attached to it, and then it will skyrocket.
-VR releases and it becomes a small success, but nothing to attract major projects to it after the year is over.
-T2 will release an update for GTA V that makes the game VR compatible. For a while, it will be the biggest seller the VR bussiness has.
-Meme Run will have a sequel. And it will be on both WiiU and NX.
