A lot of people here always scream and demand new IPs at Nintendo while spouting rehash nonsense.
Let's take a look at what Nintendo is good at. Platformers, action adventure, mini-games, strategy, and RPG. Now tell me why does Nintendo need to make another platformer and just change the protagonist, characters,etc.? Why does Nintendo need to make another action adventure game with a focus on puzzles and dungeons?
To make new game mechanics? To make it fresh? Have you played A Link Between Worlds? The Galaxy series? Nintendo always makes new game ideas and put them into their franchises. There are changes in their franchises. Sometimes it takes time sometimes it doesn't. There is no need to make a new universe and new characters. Not only are they risking their money for something a lot of people aren't familiar with, a new IP does not automatically equal to something new. It may just be a new coat of paint. Also, remember Sonic's forgettable characters?
What people here really want from Nintendo aren't new IPs. What they really want is for Nintendo to make games they aren't good at or games other companies make. Skyrim-like Zelda? shooters? A TLoU-like game?
Before you do that, ask yourself, do people demand a WRPG from Valve, a Mario/Rayman inspired platformer from Bethesda, or a visual novel from Blizzard? lol Not even the mighty Blizzard managed to release a shooter game (cancelled Starcraft Ghost). The fact that one company alone makes a lot of great games in a lot of genres is already a great feat.
