According to the IGN articles, Shinbori says it's a new engine they're using.Looks like doa5 with upgraded graphics. Same engine?
Not to worry, DOA6 will still have the hype stagesDead or Alive even the stages don't look like DOA stages...
Ihope TN show something to change my mind or I might actually sit this one out.

Together with art director Yutaka Saito, he has already thought of several more stages to implement in the game.
