In another piece with EuroGamer, Hayashi said that the characters sweat as they're fighting, and will pick up dirt as they're knocked to the ground.
Despite these additions, Team Ninja stated that the gameplay will take center stage with Dead or Alive 5.
In the third bit, from VG247, Hayashi said that his ideal cameo would be Ryo from Shenmue, as they have a long standing relationship with Sega, including the first Dead or Alive game, which was built with the Virtua Fighter arcade engine.
For those of you who want an overview of the gameplay as it stands now, EMP|Perfect Legend did a write up covering things like critical bursts, and some of the ins and outs of the characters.
