Tina, Sarah Bryant (VF) and Kokoro revealed in the E3 Trailer:
Also looks like character/costume customization, may be in which is great. Would have liked to have seen Tina & Sarah face off though or just got some gameplay of them.
EDIT: Gematsu has a gallery up.
I've always wanted to get into a fighting game and I never have. But something about Dead or Alive 5 intrigues me, it has a certain charm about it. So I actually might get this one and truly stick with it.
What Itagaki tried for happened after he left, gotta love that irony. The VF characters certainly add credibility to the game since it's generally been regarded in past versions as a "**bleep** & bruises" series. How it's recieved will determine if it lives or dies. The new TN already has a strike against it courtesy of the most recent NG title which, at best, got lukewarm reviews.
On the subject of the VF characters incorporation into DoA5. First the code will need to be flawless, both for online & offline play if they intend on doing them any justice. Secondly will be the moveset. Anyone who's played any of the VF games will tell you that each of the characters has a large moveset, which in part is one of the reasons said moves must be done precisely (the average DoA character has just under 100 moves, the typical VF character easily has double this). While with DoA the moves can be "close enough" for you to pull them off. One of 3 things will be happening in terms of the movesets:
It helps that DoAs fighting mechanics were originally patterned after the VF series.
