When making decisions regarding products, smart businesses usually look at the performance of comparables. If you're making a new present day first person shooter, you might want to see how other present day first person shooters have sold. Now, I'd be lying if I said Capcom is a smart business but surely even they might take a pause at the sales of God Eater and Toukiden (the closest comparables to MH) on PS4. They don't sell well in Japan and they don't sell well in the west. One of the excuses for the latter was that the releases to date on PS4 were clearly handheld ports. Toukiden 2 did not lead development on a handheld, a move that ultimately helped to hurt the franchise significantly in the one market that cared for the IP, to little if no gain in the west.
