Well, judging from DmC's sales, people are obviously more interested in DMC. If it could've sold 5 million, but expectations went down to 2 million, and it only reached 1.1 million... obviously DMC. Even if not a single person in the fanbase liked DmC, it still should've sold more than 1.1 million -- which shows that not only fans didn't like DmC, most people in general didn't. People are more interested in DMC. Capcom should know that.
But, I think Capcom are idiots, because they probably still don't realize that Devil May Cry fans like DMC for more than just gameplay + characters' appearance. I think that shows from how they decided to release classic skins now, AND decided to erase some of DmC's gameplay flaws. They think that if they can fix some gameplay flaws, that'll make up for everything, which is not the case. DmC still wouldn't be likable to many people, because they just don't like DmC's characters, atmosphere, style, plot, music, etc. Improving the gameplay won't change that.
They ignore fans of their series and just decide for themselves what sounds logical, and p!ss people off as a result. DMC4 is by no means representative of the DMC series. Also, it was considered the second worst DMC and there's much hate towards it, so gauging how much people want DMC to return just by looking at DMC4 SE's sales... that would be a moronic thing to do. But, I wouldn't put it past Capcom.
Please don't use sales as some sort of gauge. Don't be a suit that's out of touch with the industry. They wanted DmC to sell Call of Duty numbers, which no game in the genre could ever do to begin with. CoD only gets the numbers it does from people who literally only care about CoD. Similarly, keep in mind that used game sales are never taken into account on these sales figures, and many penny-pinching gamers have found games they love not buying a brand new copy. Sales also don't account well for acclaim, there's games like Bayonetta, the DMCs, Okami, even Godhand that are incredible games that didn't sell as well as they should have.
All in all I don't see any reason why this has to be any kind of DMC vs DmC interest thing anyway. Why the hell can't we have both? There's nothing that says we must choose, and gathering interest for both versions, for the entire series itself is way better than having to toss one into the fire so the other can be warm.
GAMES ARE COMING! LOTS OF GAMES! LET'S JUST BE HAPPY ABOUT THAT!
