They did say in the PR that they will be re-tuning the boss battles too.
As far as DMC4SE goes, I remember I did a SE wishlist a really, really long time ago but I forgot most of the points in it. It's probably too late to do one at this point but hey... if they don't use it for this they might use for DMC5.
*Pretty much every feature they put in DmC DE should be in DMC4SE as well. This includes Gods Must Die, Must Style mode, Hardcore mode, Turbo mode along with the PC LDK mode as well. This also includes some of the indepth stat tracking seen in DmC.
*Costumes, costumes and more costumes. DMC4 had 0 costumes which was disappointing so they have to make up for that. At the bare minimum I better see DMC1 and DMC3 Dante along with DMC2 Dante as well (but Capcom probably won't do that).
*Nerf Distortion and Full Steam. They can also stand to make RG slightly stronger.
*More unique areas for Dante to help further differentiate his campaign from Nero's. One of those unique areas can lead to a "dream" fight with Credo Angelo.
*A couple of unique enemies if possible.
*Vergil has his own missions in Hell sort of like DmC Vergil did that take place after DMC3. Some cutscenes as well if possible. Should be around 6 missions with a 2-3 boss fights.
*Vergil be available as a secret boss fight for Dante and Nero in some manner. Should be a much harder version of his DMC3 self (I want Capcom to fuck with his and have him turn on X Factor).
*In terms of his playstyle, I want to see him get the Doppelganger style from DmC along with some of the meatier moves combined with all of his moveset from DMC3 including Nelo Angelo mode. Give him Quicksilver style too just for the heck of it. They probably should get rid of the 0 frame Summoned Swords though.
*Co-op mode in Bloody Palace. Two players can play at once picking among the 3. Co-op Leaderboards have their own ranking of course.
*Training mode. Give us full control over enemy spawn, health, difficulty, actions along with ability to pick the environment. Ability to record inputs in training mode and play back.
*Boss rush mode. Ability to choose which boss I want to fight with which character and let me choose costume and difficulty plus modifiers.
*Ranking system needs to be reworked. No more collectibles factor in mission rankings.
*Style meter needs to decay faster. Not as bad as DmC but it's not as hard to maintain style once you achieve it.
*Confirm once and for all that Vergil is Nero's father so that we don't have to have this debate ever again.
*Fully controllable 3D camera if possible like in DmC. I know in some areas it's impossible but for a majority of areas I want a fully controllable camera especially during combat sequences.
*More aggressive AI. I know Gods Must Die is supposed to cover this but it still can't be mentioned enough. Also if possible I want to see some new moves for enemies especially in DT. Speaking of which they probably need to make changes to the enemy DT system as well because it's a very generic buff.
Anything beyond this would be amazing like legacy boss fights or weapons.
Who voiced Vergil in Marvel vs. Capcom 3? It sounded like they ripped the voice from DMC3. Wasn't really up to snuff with the rest of the cast I felt.
Same guy but he simply wasn't as motivated doing VA as Vergil for a non DMC game....
His clips from DMC3 have more impact to them.
