i think you have to rewatch Zero, he was very aware she was the pilot of the Birdhuman, he made a zoom into the "cockpit of the birdhuman" when he was approaching before Ivanov went splat.
i think by know you should know that Kawamori will enclose a serie in the last episode and then give the finger to anyone that complains by making a movie as a continuation of a serie and give the finger to anyone that complain with unsolved issues as the movie doesn't address any of this issues.
Macross is going to do what has done the last 25 years, bring a new serie or ova or movie for its next anniversary setting it between 10-30 years forward from the last installment with new characters and mecha.
Isamu and Basara will defold into action in the last episode in a massive VF-29 only for the fighter to split in two then transforming into battloid and Isamu and Basara wearing special ex-gears turn into the heads of the battloids.
Some of my friends on my area are getting to know Macross due to Frontier from Anime forums, youtube and post i do in myspace, I will try now to show them Zero, DYRL? and then start showing Frontier.
I have been thinking, could it be possible that Brera is not really Ranka's brother but his outer cyborg shell was design to look like it by Grace as well as his memory loaded with Aimo and how to play the harmonica just for him to get closer to Ranka.
