I love this rumour. It's the perfect marriage of Capcom being stupid and gamers ready to go in full meltdown mode. I hope it's true.
All jokes aside, I do want to see a more approachable MH. And if this really is true, I think that's pretty sweet. Those who want an easier MH with better graphics can buy it on PS4 or PC, those who want the traditional formula can get it on Switch. That's basic franchise expansion.
What makes this absolutely crazy is the deal behind it. If Capcom really made a deal like that with Sony, if THE next MH is PS4 exclusive, that would have great repercussions in the relationship with Nintendo. The stuff about how MH5 development is troubled while the 3DS game makes bank is just gravy.
I think this could be a terrible business decision by Capcom, but I don't work for Capcom so I'm here for the ride.
