Forum:What the difference between doa last round and doa ultimate for last gen?

yep the title pretty much sum's it all up. I know they've retained all the content from ultimate including save and unlocks and also some extra content. But why couldn't TeamNinja just port the game to current-gen and PC  with the bname Dead or Alive 5 Last Round and leave Ultimate as it is with DLC as the few extra content? That's how GTA V does it.

Did I wasted my money for that?
