Release date : May 17, 2011
Not new but possibly also not known to everyone but earlier this year the first season of First Wave has been released on DVD. Unfortunately only for region code 1, only in Canada but if you have a regionfree DVD player you will have no problem playing these discs. No extras and also NO subtitles of any kind. 22 episodes, original aired in Canada, not cuts. You can order it, amongst others, with amazon.ca. Second and third have not yet been announced unfortunately.
Update: At the moment the first season is not available on Amazon. Don't know if this will change in the near future.
