Did Dragons Dogma flop?? A decade later and no 2nd game
No idea what the original release did but the remaster alone sold 2 mill on PS4 and 360.
It also released on PC and Switch.
My point is, if it was a flop cool but they ported the game four times and made a Netflix anime based on it.
So it would seem they have some sort of interest in the franchise, but like @Anti-Anime said Hideaki Itsuno was given a choice of the next game to work on and he did "Devil May Cry 5".
Having said that, "DMC5" came out 3 years ago so that's no reason for them not to announce a sequel by now.
