I have no idea what Capcom will do or should do.
I just fear that whatever they do regarding Devil May Cry would start another war between fans. As it had already been said here, the problem is that by creating the reboot, they have divided the fanbase, and will end up disappointing one part or the other... <-- pessimist side taking over, sorry.
As for me, I didn't feel the need of a reboot, but I'm not a good judge of this, having become a fan of the series only very recently. But then DmC came out and I started appreciating it (you would laugh and facepalm if you knew what convinced me to give it a chance, even if I came to love it for its
real merits
), to the point that right now I'd rather have a DmC2 than a DMC5. But if DMC5 comes out instead of DmC2, I have no intention of letting the chance go of having some more fun with this series...
