Oh, I'm not disagreeing with that. I'm just saying that I want them to focus their efforts as much as possible so we don't end up with the issue DMC4 had - lots of backtracking, refights, limited weapons, etc. If that focus leads to only one or two characters, so be it. I don't think that will end up being the case, either way, I'm just sayin' where my preferences would lie.
Personally, I'm someone who is perfectly fine with them reusing actual assets and stuff from DMC4(Just use the same models and animations of Rebellion/E&I/Coyote-A, bring back Assaults/Frosts/Blitz, make Gilgamesh/Lucifer/Pandora unlockable, and what have you) so they can focus their attention on genuinely new stuff. I really don't want them to spend time and effort into making a new cool boss only for them to drop a weapon that is functionally identical to Beowulf/Gilgamesh when they could have done something new.
