Let's talk about party members. So based on that title art it looks like the two girls and the heropon make up your initial party.
So what do people think? I think it's pretty interesting that if the main character is female that will make all three initial human characters female. Something I don't think I've seen in an RPG with both genders in the party.
As for future characters I'm really interested to see if they include a large number of alien species playable. In the following screenshot you see two distinct types of aliens just hanging out in New Los Angeles. I think these might be immigrants to Earth that arne't from either of the warring alien armies.
Look at the trailer from E3. There is one alien dude in a mech combat nodding. Then there are two more animal looking aliens (a red male and purple female) later in the trailer. They look very distinct but I wonder if any are of the same race as another.

Also there is that sequence in the trailer where everybody nods. Elsa and the black-haired girl are there I wonder her many others are party characters too? My guess is the alien guy and the final guy with black hair. The other three people seemed less detailed and too generic to be party members.
