On September 14, 2011 Team Ninja has released the Pre-Alpha trailer for Dead or Alive 5. The trailer shows off a dangerzone filled construction yard rooftop with Hayate and Hayabusa dueling it out. It should be expected that many of the attacks and motions are from Dead or Alive 4 as pre-alpha builds tend to carry over a lot from the previous version as other system mechanics are ironed out and developed. At the same time it should be warned that anything shown during the trailer could be changed once the final build arrives.
Team NINJA has set out to claim the game as "fighting entertainment", and honestly it makes me feel that the series has returned to the DOA3 style of grittiness that I personally have enjoyed. There's not much core gameplay information to be found at this time as it appears at first glance to be a consolized Dead or Alive Dimensions. I only caught two new gameplay mechanics that stood out: After hitting the dangerzone wall, Hayabusa bounced back into the ring instead of staying on the wall; Hayate did a charge attack reminiscent of the Ninja Gaiden series' Ninpo attack that did a canned animation sequence that could be their answer to "Supers/Ultras" of other games but no HUD is displayed to determine what was canned or not.
I look forward to breaking down the trailer once it's available, but for now I'll leave you with the promotional poster showing off Kasumi/HItomi:
