"I would like to ask about the current situation of "MHW". As of the end of September 2018, we have sold 10.7 million copies in total, and about 70% of the total is sold abroad. In Japan, teenagers are increasing more than our expectation."
They also site good sales of the PC version. It's great to see the steam community embracing Monster Hunter and it's great to see the Xbox and Ps4 too. Sales outside Japan are excellent. Capcom have done a stellar job in transitioning this IP. Who knows how high sales will go.
