Thanks for the great images darkplataform
Kresphy posted something at MW forums, I think it's an Animadia article with Kawamori commenting about certain things from the movie like the triangle, Alto's fate, Sheryl and Ranka.
And as always he posted it in japanese
so I hope someone could please translate some of it.
He also comments that Frontier is now complete but there will be a magical girl Ranka spinoff (?) and then about the 30 anniversary of Macross next year
