Monster Hunter is in decline which is why they are in trouble yet again. They have a breakout hit, milk it to death at the detriment of other new IP and then it becomes a situation where their market cap tanks because all at once, nothing is selling well.
Capcom has been repeating this cycle forever except this time, they have the extra baggage of a failed mobile division and failed overseas development. Any project headed up by the Japanese working with overseas devs will 99.9% of the time fail. The Japanese (yes, this is a stereotype) are just not well equipped/experienced to handle cultural, time zone, work ethic differences to make a successful title especially when you have parallel distributed development.
Konami, for all of their suckiness, diversified their portfolio to include gambling, gyms, mobile games in addition to cutting down investment on their flagging console and arcade games.
