Wow I thought it fell into dev hell and wouldn't be heard from again.
It will be interesting to see just *WHAT* they actually have the rights to use on-screen. There's been decades of legal fights which I thought resulted in Harmony Gold retaining the right to market and release any footage from the Macross series, edit footage for releases, but they were no longer legally able to create new footage involving any of the characters, names, vehicles, etc... from the Macross series.
So where does this leave the movie? The iconic image for Robotech is the ship (Macross) and the Valkyrie (called Veritech in Robotech). Can these things even be used in the movie?
