There does seem to be mechs or exoskeletons at least in the trailer. The focus on air combat tends to be a limitation for most interpretations of space settings. There is the possibility for large space station interior settings where "ground" vehicle combat should be possible without necessarily removing air combat though flyboys would obviously prefer the advantage of open space.
That's one of the things I am not liking about what I am seeing.
If you watch the trailers you see our hero jumping into a fighter. And you see him in his fighter attacking enemies in LEO. This is a problem.
Space Fighters are a Overused Scifi Troupe that has no science legs to stand on. Hard science says that a space fighter is a flying Coffin, Why? Because in the microgravity environ The Advantages of the fighter vanish.
The key advantage of the fighter in a atmosphere with a surface is that the fighter has far more Delta V then 90% of it's targets. This means that a fighter can out run or outManeuver most attacks, against slow surface targets it can change vectors and engage from almost unlimited angles.
Against a Equal target IE a fighter the key advantage is that both fighters pack enough firepower to demolish each other in a single action.
When you start dealing with microgravity suddenly those advantages are gone.
Large Capital ships would have equal delta V to any space fighter along with longer range. A space fighter has no speed edge vs a Capital ship the ability to perform sharp maneuvers is is also equalized as move for move a capital ship would be able to turn and burn equally.
Finally the capital ships would have the advantages all in it's favor. It's shear mass and likely addition of armor in the form of Whipple shields would render all of the space Fighters heavy weapons imputent, Where as a single hit from a space capital ship's arsenal would shred a space fighter like swatting a Mosquito. Farther more the short range of the space fighter would also render then useless as Capital ships with a longer range could in a solar system stand off and attack targets from orbit using heavier weapons like large caliber high velocity Rails guns and missile. Detection of launching fighters and capital ships like that seen in the trailer would be easy using the same IR sensor tech used today to watch for ICBM launches.
Upon detection capital ships would shell incoming adversaries and their space port. Additionally the biggest issue I have is the lack of Hard science in the form of having large capital ships like carriers as SSTOs. Due to gravity on earth you could never ever really have a large craft launch from land to orbit with out a massive amount of help on earth. on a smaller lighter planet or moon sure but landing something like a Carrier is impossible, It's a problem I also have with the new Star trek movies.
If it was a smaller type like a Destroyer or frigate or Cutter equivalent sure but a large carrier? then there is the shape of the craft seen in the trailers the most logical shape for a large space capital ship would be a cylinder not a boxy shape. What we see in the trailers is basically the helicarrier from the Avengers.
