This trailer feels like it was meant for the action game fans; there aren't the usual trappings that would attract or pique the interest of someone who wasn't already into the genre or Platinumgames' output. There isn't even a single voiceover, I'd consider this a teaser as opposed to a trailer.
From what's been shown I think there might not be a dedicated jump button (again). It does have launchers, air combos and even a move that lets you phase (think Air Trick from DMC).
Level design looks visually interesting and combat arenas are spacious. I suppose arena barriers will be in but I'd be pleasantly surprised if they weren't. Would make it more like Souls or Ninja Gaiden where you can take the battle to a different location if you want.
Not a fan of how the wound slashes on the enemies don't line up exactly with the sword slashes. Maybe it gets in the way of visual clarity.
Lots of low end boom in the sound design too, reminds me of how MGR sounds when you trigger zandatsus.
Character designs are fairly vanilla with one distinct item common to them:
The thingamajig on the character's back seems to be this game's version of Astral Chain's Legatus. It appears to control your phantom swords and is capable of grappling then pulling yourself forward, obtaining resources from an enemy and even wielding their weapon against them.
Final part of the video is Rules of Nature + the finishing sequence vs MG Excelsus.
