I don't think people should look at these as early builds. What we're seeing here isn't, for example, original DMC game/DMC4 port for Wii, as in the actual game that would have been made. These are likely just prototypes made for when pitching the project to the publisher. If I'm not mistaken, most or all of the work we see here would have been scrapped for the actual project development. Someone correct me if I'm wrong.
