it would be better for the game if which rumors are false?
7 squaddies is too little if 2 generic human sidekicks and a member of nearly every Milky Way race will be included.
1) Drack Krogan
2) Female human sidekick
3) Male human sidekick
4) Synthetic (2 had Legion, 3 had EDI)
5) Blue Tentacle Head
6) Salarian
7) Turian
If Bioware sticks to tradition and fan demand with the squad roster, we get no new alien races as out teammates.
Not everyone has to be a squadmate. We can have non-combatant crewmen.
"Generic humans"? I like my human crew, being a human myself. [Edit: I'm not big on the romance arcs, so this isn't huge for me, but my protag won't get down with weird ass aliens. That's nasty. So, no humans means no romance side content, for me. Again, minor loss, but still...]
I'm sure they will leave room for new aliens. They kind of know what they're doing. They created this whole thing.
