TLDR version of the trailer:
*DMC crew getting washed by the main bad guy. Everyone including Dante gets destroyed, with Dante having his signature sword Rebellion crushed even when he was going all out with Devil Trigger. More on this later.
*Bunch of new Buster animations for Nero including a flashy one where he is counter countering an enemy in mid air with a bunch of exchanges before finally putting it down.
*A bunch of new enemies shown including a couple of new bosses like the chicken demon boss thing.
*Does an impale on a new fairly large boss type and then had blood all over him. Not sure if a boss or a sub boss.
*V game play stuff is hard to talk about without getting hands on. He has a panther and bird as default, probably for his basic attacks. Panther has moves that work like Shadows from DMC1 where it can morph its body for attacks. The bird has more projectile based attacks. V himself can summon spells and teleport around, even do counters of sorts. His version of lock on colors the enemy white/purplish or it may be some sort of debuff. He can summon a giant slimy looking demon that can wrestle big body enemies, break through environments and shoot a giant beam. Vs spells including summoning swords, spikes and a giant meteor. The environment destruction at display looks really nice.
*I guess V's devil trigger is him getting white hair like Dante in DmC.
*Dante's section is stuff we have seen before though there were a couple of new enemy types shown. He has a conversation with what is most likely King Cerberus in some icy environments. Definitely a boss fight and probably with all 3 elements and the boss is unchained this time... should be a hype fight!
*There are sections where characters are fighting similar bosses/enemies in similar environments to other characters, confirming that you can actually choose which character you want to play as in certain missions (if the choice is provided). We see V fighting Angelo and Goliath, we also know that he was present there in terms of story.
*Some sections with Nero and V in the same game play section! V is shown to be running faster than Nero! They are comboing off of each other.
*Sections with Dante, Nero AND V in the same game play area and they are all comboing each other! How is the game able to hold 60FPS with so much on screen!!!
*Dante fighting some fiery demon looking thing in the icy cavern, maybe that's the fire head of King Cerberus?
*The money shot is Dante in his MAJIN Devil Trigger (from DMC2, this takes place after DMC2) with a BRAND NEW sword! Maybe this is Rebellion reforged or a new form of Sparda? Very interesting lore wise nonetheless! Surprised they actually spoiled this.
*Bloody Palace and demo are cool, wished we had gotten BP day 1 though.
