Yes, but the how is kind of important.Didn't DMC1 text introduction cutscene say that he died?
There in fact is a war happening after Mundus was sealed again, Sid talked about it, so the idea is already there and they just need to expand on it.Indeed, playing the first game i thought that was it. Dante avenged his father and stopped Mundus. I didn't think he would have such a big impact in the other games.
It would be cool to see a civil war between the demons to try and replace Mundus. Or anything really, There's a lot of room for a sequel in both DMC and DmC.
