Isn't it obvious?
Their comments about their sales expectations shows that they had high hopes for this game.
They expected it to sell 5 mil If I'm not mistaken.
It didn't sell even close to that.
EDIT
actually it was 2 mil, but still didn't reach their goal.
I heard that Capcom originally said they wanted 5 million copies of DmC before it's reveal and then after the massive backlash on its reveal, they lowered their expectations to 2 million, then after the horrible sales, it went down to 1.2 and now after firing the western devs, it's down to 1.15.
I think that since Capcom has switched to internal development now, I think they're gonna try and mix DMC5 and DmC2 into one game, like maybe bring back the original Dante, with Reuben Langdon as Dante, his iconic look with white hair, red coat, original Sword, original Ebony and Ivory, the cocky attitude and everything else he's supposed to be and they'll throw him into the DmC storyline with a bit of story tweaking so they can get original Trish, Lady and such in there.
But I really hope they don't do that, trying to please everyone has already blown up in Capcom's face.
