That's what they get for willingly pissing off the majority of it's long time fans. The bad sales are a good thing for antis though, because now that Capcom knows they aren't making any money off of this series, they are most likely going to make a DMC5 next, because there's no way they're going to shelf one of their top-selling franchises.
Worst case scenario, Capcom will end up going under because of their games no longer selling, due to making games they know their fans don't want. It would be the definition of bitter irony if one of the most loved companies in the 90's that became one of the biggest gaming companies, then became one of the greediest and stopped making money indirectly because all they were after was a profit.
You don't know capcom. They see a franchise not doing well, they ax it.
I thought Asura's Wrath was very cool. Sure it was a quick time heavy game, but it was so badass. The DLC ending did kind of hurt them, but i would much rather get a DLC ending, than keep the cliffhanger ending and hope for a sequel we never would have gotten.
Really the only Capcom property i am happy with right now is Dead Rising. Now just gotta wait until they screw that franchise up, or reboot and kill it. Actually right now would be perfect for Capcom to reboot, just like DMC4 they have a ton of loose ends in Dead Rising, Capcom can just forget about those, piss off fans and reboot.
