Siliconera got some hands on time with the latest build of Dead or Alive 5 that includes Virtua Fighter guest characters Akira Yuki and Sarah Bryant. The impressions are fairly simple and it sounds like they only got a match or two in with each character. They mention that Sarah has great range with her kick attacks but Akira felt "too stiff" compared to the rest of the cast.
While I'd take the individual character impressions with a grain of salt, they do talk in depth about the Power Blow and Critical Attacks that allow you to dish out massive damage by using the walls and other environmental elements of each stage.
