I agree with this.
Capcom said the game was incomplete with things, so it makes me question why didn't they try to complete it during the process of DmC? Ninja Theory was doing gameplay AND the rest of it. Capcom could've gotten to work on adding new things to DMC4 during like Dante's own levels, getting rid of the dice game for something better, no long backtracking, better platforming, etc etc. if DMC4 took 3 years from DMC3, then 6 years would be plenty to do more with it. Adding new characters is fine and awesome too, but that doesn't excuse the other aspects that held it down. It's basically copy and pasting the PC version to the console version with three new characters and a few small cutscenes (I assume because there could be secret cutscenes that they haven't told us yet) in it.
