Capcom shareholder call confirms Monster Hunter World isn't coming to the Switch but there IS a Monster Hunter game "geared for high school students" which probably means not something freemium like the mobile stuff they said targeted 'older consumers with less time'.
Theres been rumours of something like a "Portable 4th/Freedom 3" and i would not be surprised for something that takes generations more action heavy side and goes more in that direction to differentiate from World as the mainline brand flagship title. Personally i just want to see the spiders, crabs, birds and the like make a return. Iceborn brought some nice stuff in but theres only so many wyverns you can fight before you want something different. It would be nice so see stuff like Nakarkos again since that didn't really get a great fight in generations but also the rapier and herding dog 'weapon' would be pretty cool if it goes more action leaning.
