@Foxtrot94: Your concerns seem to mostly stem from the general impression DmC originally left behind regarding difficultly and how OP characters are in DMC 4: Special Edition.
And since you agree that DmC: Definitive Edition does up the difficulty setting, I would say that they'd probably keep to that when working out DmC 2. So most of this is trying to speculate whether or not they're going to make the games easier/better suited for beginners. In my opinion, probably not. Not just based on what I said about DmC: DE, but also because I don't think them making DMC 4: Special Edition 'more challenging' was in their interests.
Now let's say they're planning something with DMC 5. I'd reckon most of their efforts would be concentrated on that. Therefore it would of been less of an interest to make a 7-8 year old game difficult for us, when we've all beaten it already and know the story. Yes of course, I agree that being OP makes the game less challenging. But it's not like we really gain much for our struggle to complete it. New costumes and such aside. The game was just for fun, to give us new playable characters and to tease and tantalise us. Regardless as to if they've got anything planned for DMC 5 or not, I'm just assuming that difficultly or focus on making it challenging wasn't their biggest point to make. I could very well be wrong, but that's just how I see it.
