It's still a musou game. I don't think it will reach that high.Having said that, I do expect it to be one of the best selling musous out there, maybe even the best. Something like 5 million units is within the realm os possibility, I would wager.
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
