As they say, about time and welcome aboard!
So you know, the upcoming movie is NOT a mixdown of the 26 episodes, it's an entirely new film. Nobody, NOBODY knows what it's going to be about. Izubuchi has said in any number of interviews that he wanted to do a movie about the Battle of Mars, where Okita somehow managed to hold the line and beat the Gamilas back to the outer system.
But this may not be the case. It may be a 'side story' taking place during the journey to Iscandar, or a "meanwhile, this happened" or, well, just about anything.
I think it's safe to believe it will involve the Yamato and the crew.
On the carriers, if you watch again, the fighters don't dip when they launch, only the heavy torpedo bombers and the drill missile carrier dipped after launch.
And it's completely possible that one of Domeru's carriers survived. We see it dip into a nebula but we never see it explode. That could be interesting.
One thing about Yamato's fighter launch system, did you notice that we've never actually seen the Cosmo Falcons being retrieved/landing? The Type 100, the Seagull and the Zero? Yep. Not the Falcons. I can't even figure out how it would work and that's after pouring over the model sheets for hours and hours. I think they may have just 'handwaved' that difficult thing away.
