Here's my 2 cents.
Henry Ford once said that if he asked people what they wanted they would've said a faster horse. Obviously while talking about the car Ford pointed out an aspect of human nature that is more prominent of our times of technology since we are moving so fast, but this applies to the other parts of us that you imght say qulify here.
However, NT has not shown anything that is so beyond what we already have to justify calling them car (new) and horse (original). The gameplay we've seen doesn't look like it's going to be much more advance than 4, just diferent. The visuals are nice but sacrifices had to be made. Actually, the biggest diference we've seen so far is a cosmetic one, nothing else. Yeah, the buttons are diferent and the styles are gone but that's not affected the core gameplay, you can play this the same way you played the last 4 games and all you have to do is get used to the new botton scheme. The new angel/demon switch isn't as big a leap forward as it's been played to be, and there are not that many new things in this game that you couldn't do in the others.
This is all supossed to be a reaction to DMC4, right? Because of the poor reception of DMC4 by fans and critics? Well, it wasn't the way the game looked that was the issue, it was how it played and how the story was told. The game was, in so many ways, a step back from 3, which was a PS2 title, so that shouldn't be, and that just sucks, I mean, come on!!! The story style worked well in 3 but it was just not doing 4 any favors but is Capcom really so unflexible that they couldn't think of any other ways to change the series than to throw everything away and give it to someone else? I honestly think that they weren't getting what the problem was, that they are trying to fix the wrong things and failing to see, or maybe refusing to see, where the probles lay.
Well, that's what I think, not something they'd agree with but it is what I think they are missing.
