Nintendo has offered more details on their plans for E3 2016 and it will all boil down to two streams from the developer. Unfortunately, the details did not mention Nintendo's next home console, codenamed the NX, but it did include one of the first announced games for the NX — The Legend of Zelda.
On June 14th at 9:00 AM PT, Nintendo will be hosting a livestream of gameplay for both The Legend of Zelda for Wii U and Pokemon Sun and Moon on Twitch, YouTube and their own E3 hub.
Nintendo officially announced that the previously Wii U exclusive, The Legend of Zelda, has been delayed until the release of the NX in March and will be hitting both Nintendo consoles (Wii U and NX). However during E3 2016, Nintendo will only be focusing on the Wii U version of the port.
On June 15th at 10:00 AM PT, Nintendo will host a livestream for upcoming Wii U and 3DS games, including Monster Hunter Generations, Dragon Quest VII: Fragments of the Forgotten Past and Tokyo Mirage Sessions #FE. The beginning of the stream will focus on Pokemon GO, the highly anticipated mobile Pokemon game.
