No, I don't. Just a hunch. They knew DmC wouldn't do well, so they'd probably work on something to follow up. Gotta strike while the iron is hot, right? They can rebound from this hatred by giving people what they want, easily.
That, or they're just gonna put the series on break for a bit.
I liked DmC, but it had NOTHING on DMC3, and not as much as DMC4. The platforming and art (played on PC) didn't do wonders on me.
