Looking at Wikipedia:
It seems Sheena's voice actress Jennifer Hale did a voice for Soul Caliber IV, so there is a good chance Namco will use here again.
Wikipedia also lists Tara Strong as the voice actress for Presea and Aqua (Not real evidence but it could be true) http://en.wikipedia.org/wiki/Tara_Strong
Couldn't find any evidence that Zelos and Regal's voice actors have worked with Namco recently, so I'm a little worried about them.
