I'm not going to get in to this P* debate because I extremely disagree with so much been said and I'm tired of this argument but I think this thread has been under thought since people are actually considering it.
DmC is not DMC, I don't care how many people say that it is, let's start with that. So many of the things that make a DMC game a DMC game are lacking here and all the things that are there from the previous games are only a part of the whole, not enough to considered the same after all that was replaces. It's a very superficial 'it's the same thing.' Now, in the same vain of this idea, if you want a DmC sequel then it has to be NT, otherwise it won't be DmC, it will be someone's interpretation of it, in the same way it is not DMC; the flavor and the idiosyncrasies that makes it what it is will be lacking, it will be just off enough that you know it's not the same and you'll hear from others that it is a DmC game because it has all the stuff on a check list even though you know it lack the qualities you look for in DmC.
There is no one else to make a DmC game except NT. There is no getting around it and passing it to someone else. You want more of that you go to who give it to you in the first place, otherwise you are going to get something else.
