Alright, going through the trailer frame by frame.
Video starts out with Hayabusa on a tree top - eerily similar to the DOA4 trailer
Ayane opens with

3

k / While Running :kand blocked by Raidou
Raidou follows with :k but Ayane recovers faster with

1 and it apparently ducks highs?
Raidou continues his string with another :k which Ayane continues to duck
Raidou recovers and Ayane does

p

k (which doesn't guard break) :k - I forget if it guard broke before, maybe in DOA4's trailer
Ayane attempts

p but is counter hit with by Raidou with what looks like Leon's

+:k which puts her into a fall forward stun
Raidou continues stun with a hell stab like move similar to Bass (

+:k)- it doesn't look like string though - the hit apparently puts Ayane into the typical counter hit hell stab stun
Raidou continues stun with a forward elbow similar to Akira from VF, putting Ayane into a stomach stun (not crumple)
Raidou goes straight into a throw while either Ayane is still in stun, or just comes out of stun. I don't see a recover stun animation though - so it might be a hit-throw. The throw is similar to Kasumi's

3

+
Posting so far as I go through Kasumi's kata scene - which I wouldn't be surprised is the same animations from DOA2 opening.
Okay, back to the fighting:
Hayate's

1

p

is blocked by Raidou.
Hayate free cancels into some move - can't tell (possibly

p) - but is interrupted by Raidou's hell stab. Which I assume hits high, but Hayate is damn near crouching - making me think Hayate's attack isn't a high crush.
Hayate gets put in the face stun that Hayate's

p does.
Raidou continues stun with a lift stun - move looks like a

3

motion, but could just be a

p as most double direction crouch attacks are launchers on stun/ch
Raidou does Hayate's DOA4

p

which knocks down/back
Hayate immediately techs up and away (without wake-up kick?!) from Raidou without going into a wake-up game
Raidou performs a huge/fast freestep while Hayate gets up
Hayate performs his DOA3

6b

2:k (stance switches - which says the

6b, not

6), the elbow is blocked and the kick connects causing a trip stun. The string was not a 2 in 1 as Raidou recovered from blocking - he could have blocked the trip.
Ayane tags in (Tag system? 2 on 1?)
Ayane continues stun from trip stun with

k

k. In DOA2 and DOA3 this would have caused a knock down to Raidou, I forget what it does in DOA4.
Again! Ayane grabs Raidou without Raidou appearing to be recovered from stun yet. She performs a tag throw to Hayate.
Cut back to Kasumi apparently not wanting to defend her brother from her damn uncle.
Okay, Hayate and Raidou are spaced apart again - freestepping each other.
Hayate goes for a throw but is hi-counter blown by Raidou's previous

3

or

p - which now(!?) launches.
Hayate is juggled off a low height with what looks like a

p

p string by Raidou. Don't know if this is all one string (

3

4

6

) - I don't think it's a full string but

p

p is definitely a string.
Hayate again immediately techs away from Raidou - without wake-up kick.
Hayate performs his DOA4

p wave dash starter - dodging Raidou's Bass like power gong (

p)
Hayate continues the wave dash into his

elbow which stomach stuns Raidou.
Hayate continues stun with his DOA4

p

- causing the same stun extensions from DOA4
Hayate tries going for his

p but is defensive held by Raidou - out of Raidou's stun. The DH performs just as Gen Fu's High Punch Defensive Hold.
Hayate techs back up without wake-up kick
Both Raidou and Hayate freestep into the same direction
Hayate performs his

3

k, but is defensive held by Raidou - which is a hold resistant attack and puts Raidou to Hayate's
right - note: not straight behind him.
Raidou punishes Hayate's attack with a Kasumi

k like attack - putting Hayate into a lift stun
Raidou extends the stun with Gen Fu's

k, causing Hayate to be put into a stomach stun.
Raidou string attacks from the

k to an uppercut launching Punch
Raidou juggles with Gen Fu's

p

k, causing knockback to Hayate who tech rolls into cinematic of Raidou performing an energy blast similar to Hayate's energy blast in DOA3's trailer. Could be the Torn Sky Blast from DOA2U's opening.
Hayate and Ayane are knocked down the slope into a new zone of the arena.
