As far as a reboot, I would have liked a FPS or TPS, set in a reimagined DMC universe. It would have co-existed and not infringed upon the older games' territory. I would have liked something like "The Darkness" where you control devil powers and your guns. Maybe make Dante a hitman that works for demons, or something. Of course, something would go awry and he would be fighting the demons near the end.
That suspenders design would have gone great with it.
