|Mass Effect 3 is the third installment in a huge epic science fiction trilogy, it continues were Mass Effect 1 and 2 left off. All choices carried from ME1 to ME2 and choices carried from ME2 to ME3 will impact what happens. This is a prediction of Mass Effect 3's character rooster.|
Mass Effect 3 Squad Members:
Tali'Zorah Vas Normandy (if still alive after ME2, popular, male love interest)
Liara T'Soni (guaranteed alive at start of ME3, popular, male/female love interest)
Garrus Vakarian (if still alive after ME2, popular, female love interest)
Miranda Lawson (if still alive after ME2, high profile)
Legion (if still alive after ME2, popular)
Mordin Solus (if still alive after ME2, popular)
Mass Effect 3 Squad Members/Character Appearances:
These are love interests but it's still possible they may not be available as squad members in ME3.
Jacob Taylor (if still alive after ME2)
Thane Krios (if still alive after ME2)
Jack (if still alive after ME2)
Ashley Williams (if alive after ME1, was not a squad member in ME2)
Kaidan Alenko (if alive after ME1, was not a squad member in ME2)
Mass Effect 3 Character Appearances:
Urdnot Wrex (if still alive after ME1, was not a squad member in ME2, if alive he's a potential leader of his race)
Kasumi Goto (if still alive after ME2, optional due to DLC)
Zaeed Massani (if still alive after ME2, optional due to DLC)
Morinth (if still alive after ME2, optional alternative due to personal quest)
Samara (if still alive after ME2, optional alternative due to personal quest)
Grunt (if still alive after ME2)
I think the 6 most likely squad mates are those listed first, although personally I'd rather see Miranda swapped with Ashley/Kaidan as they where glossed over in ME2. Reason for not putting the next 5 as as likely candidates is due to them being introduced in ME2 or not as popular as the first 6, or that some (Ashley/Kaidan) could be killed during ME1 thus adding complexity. (fully storied character not used at all in ME3 due to ME1 choice for example)
All characters will make appearance though even the DLC only ones. And to varying degrees. Some may even be non-friendly/potential enemies at some point or not.
Possible conflict with Liara (if romanced in ME1 and some other character was romanced in ME2).
Garrus, Mordin, Legion, Tali are rather popular so most likely recruit-able in ME3.
Liara is guaranteed to be alive in ME3 so she will be there and since she was not recruit-able in ME2 it's most likely she will be in ME3. In ME2 with the DLCs the squad was rather large, in ME3 the squad is likely half as large due to both cost and to allow deepening the personal stories of characters,
as well as resolving possible love interest plots.
I will be very surprised if there are any new squad characters added in ME3. Only reason I can think of is to shake up the dynamics of the squad somewhat, but this can be done by re-introducing Ashley/Kaidan (if she/he survived ME1) instead.
I certainly do not envy the writers that are juggling this plot "web", good luck guys/gals.
