Picking up about the M-25 fleet, that REALLY REALLY cool zoom-in showing the Ghost deployment on the tactical view shows clearly to me that Macross 25 is a single ship. The "pill ships" we're talking about seem to be oversized Aschio-type modules that were built, as needed, trailing from the main ship. There isn't much rhyme or reason to the number of modules, which seem built randomly with a different number of "pills" in each of the two branches trailing from the main City module.
As to why M-25 doesn't have several colony ships like M-7, I figure it's just how the ships ergonmically grow out of neccessity and according to the needs of its colonists, rather than as a standard "fleet" deployment. It seems understood that transportation between the various fleets is possible, and in MF an even routine occurence. It would be astronomically expensive to ship someone from Earth, but all the various fleets would still in general be in contact with Earth unless Something Bad happens to them.
Point being, that M-25 could be a simple colony ship not unlike Megaroad-01. It would be generally self sufficient, but would have all the life-support systems, recreation facilities, science labs, etc. contained within to begin with. Then there's other fleets like M-7, which have specialized ships giving some fleets some additional oomph in certain areas. So, M-7 might be more priviledged in having an entire ship dedicated to movies, or training, or what-have-you. Each fleet operates to an extent as a city-state, just as we have here; but Inasmuch as the United States all of Hollywood, Canada has part of Vancouver. Six of one, half a dozen of the other.
But on that note, are there any shots of the tactical displays we see available, made by some of the folks here? I haven't seen any yet...
