Costumes in real 3D

The rumored Dead or Alive 5 was a no show at E3, but the consolation prize is not too shabby. Dead or Alive for the Nintendo 3DS will be based on the fighting game series and not the beach volleyball side stories. It had to be tempting for Tecmo/Koei to offer the voyeuristic thrills of DOA Xtreme in 3D(!) so hats off to this tasteful show of restraint, at least for the launch of the system anyway.

Aside from some screens, no solid information is available. Is this a port of one of the existing installments or something brand new? I'm putting my money on a modified version of Dead or Alive 2 from the Xbox Ultimate collection with perhaps some new characters.
