According to the updated Dead or Alive 5 official website, it appears that DOA5 will have more than one version released. The website states that you can preorder the "standard edition" from various retailers. Honestly, I find this shockingly expected. I look forward to hearing what other editions are announced and their offerings. Hopefully they won't have gameplay altering exclusive DLC (such as characters or stages) as that's always a low blow. Dead or Alive 5 is scheduled for release in September of 2012.
