I really hope DMC5 gets developed. The series deserves an actual ending, and Nero deserves to go through change and mature. It would be nice if he actually became as powerful as Dante, because DMC4 sort of ****ed me off saying he's 'not in the same league'. Really... so I'm supposed to like playing as a weakling? And what about the inconsistency between the damage he does in-game vs the cutscenes? And why doesn't he have a Devil Trigger? Why a hovering ghost that looks exactly like the Devil Trigger he was supposed to get? DMC4 is confusing and maddening.
I hope Nero gets to be awesome and gets awesome weaponry. A spear? Yes, please. Or maybe a huge 'summoned spear', instead of the summoned swords. So much fun, just chucking a spear at demons. The Yamato would be used like in DMC3. The Devil Bringer can go get infected and die off, unless there's some way to explain why it even exists.
Like I said, give Nero his original Devil Trigger back. And... maybe an armored DT, sort of like Dante's Dreadnought form. However, this form will look like Nero Angelo, to further illustrate that Vergil is (probably) with him.
TWOxACROSS's plot sounds good. I'm not much of a writer, so it sounds fine. However, it could do without the melodramatic 'Dante sees his past and skideedle flash before his eyes'. Moreover, I'm not sure DMC2 needs to be brought into the mix. I'd rather see Dante act like he always has, because I do not find his change from DMC3 to DMC2 personality believable.
Capcom'll probably have to put one of the games on hold. Can't imagine DmC2 and DMC5 being made simultaneously. Would probably be boring to the staff, as well.
