Nintendo should have asked this before the 1st time they started development of MP4.
It would be interesting to see if they take any of the lessons from BotW into MP4. I could really go for a 3rd person open-world game if they could design a planet in an interesting way and properly gating off areas until the required upgrades. Or take some of the tech from Star Citizen and give us multiple planets to travel too with vastly distinct biomes. There's a lot of possibilities with the franchise. Hell, it's gonna be interesting to see how Halo Infinite is when it releases, as Prime, while following it's own unique design and mantras, was def. trying to compete with Halo. And if Infinite has some great ideas, Prime could expand on them.
