DMC is dead to be honest. Capcom doesn't care much for the serie anymore. The storyline is also a mess.
THIS IS FACT:
They said if NT wasnt around they probably wouldnt have made DMC game.
And the fact they decided to reboot and reject Dante is ultimate betrayal of the things us fans like.
They even replaced him to certain degree.
I'm sorry I have to comment on this, just for something I remember my dad saying once some years ago.
Something can be really good, like a film, book, game or a tv series, but there will
always come a point when a creator/director/writer/etc have to know when to end it [e.g: you can get one really good film, and then a sequel/sequels to it that are utter crap]. Sometimes you can have something go on for so long that it eventually loses what made it so good in the beginning, and DMC4 might've been a little red flag to that.
Maybe there could've been a Devil May Cry 5. A lot of fans have mentioned ideas and where they could've gone with it [even a Sparda prequel that many talked about] but by the sources you sent above, it seems like Capcom weren't confident enough that they could pull off a DMC5 successfully, and still make a decent quality game worthy of being DMC. Sometimes you just need to know when to pull the plug or start from scratch, because otherwises you gets series like Resident Evil that's nearly gone off track from it's survival horror roots, and even Tomb Raider that was losing it's way with it's last title before it got rebooted with the new one.
I don't think it is that they didn't care, far from it, I just don't believe they knew what to do with Devil May Cry anymore [and people can argue and debate otherwise, but that's how they felt]. They'd already attempt one mini reboot with DMC3 after what was DMC2 [which, was more Lucia's story than Dante's, because the plot focus more around her.] After DMC4, they might've needed to attempt a second mini reboot in that universe, and that could've been where Capcom just completely ran out of ideas. [What was it, about two years after DMC4 before DmC got announced? So cutting back the time it took them to approach Ninja Theory and any other gaming companies at that time, that's got to be about a year or so on the drawing board trying to figure something out? And what about the time during DMC4's production? Surely they should've been planning at that time what to do afterwards, so that could be an additional 6 months or an extra year or so topped on that.]
Could they have done a full remake then on all the DMC titles? [Would they even
need them?] If they'd decided on that then it means they'd of had to have to go through Devil May Cry 3 again [which only got released about 2 years or so earlier before DMC4, a much longer period of time before Resident Evil 1 got a remake] then you would've had to have visited DMC1 again, and then you're back at DMC4 before going onto DMC2. Sure they could've had other plot elements thrown in to make other sequels, but they would have still needed to cross previous titles and go through the same plot, more-or-less the same scenes with some dialogue changes. And what would they have achieved? Better graphics? Some minor plot differences? Improved gameplay? Would that have been enough? Even so, you'd still be waiting years to continue on from DMC4.
So ultimate betrayal is the most overdramatic comment for a company using their heads. They didn't want to attempt to make a DMC5 or a DMC6 if they couldn't do them justice [and probably would've had fans raging at how terrible they were too, just like people have complained about Resident Evil 6]. And after seeing some games, films and shows out there live on longer than they should have or start to lose their spark, I'm glad they decided to reboot the whole thing, I don't think I could've beared another DMC4 and a Dante that became invincible, rather than the part human he was in the first game.
The only thing I wish is that they'd made DmC a bit more familiar for fans from the originals instead of n00bs to the series like me [even if I did know about the series prior and had seen footage on the games] because even I'll admit it does drop you in there. I just hope that's something they'd take into consideration for a sequel.
