From what I gather in ME3....Here are some of the confirmed squadmembers.
**SPOILERS BELOW IN REGARDS TO PARTY MEMBERS**
4.Tali (confirmed by Hudson)
5.James Vega (James Sanders is now known as James Vega!)
So that's 5 confirmed squadmembers, below are some speculations
6:Jack - Seems to have gone through a massive change in hairstyle for the next game, also less hardcore, as stated by some of the devs (Hudson?) and alot of the new information released is on Jack.
7.Krogan - I can't confirmed who but it could be either Grunt or Wrex. I'm telling ya, THERE IS NO WAY they won't include a krogan! Krogan are like the second most important party members in any ME game, and I don't see any reason not to put them in. I just can't tell which krogan will be in the party though : ( Smash me if I'm wrong.
8.Salarian - I'd be dissappointed if there aren't any salarian, but we'll see. I want Mordin back so bad *sniff*
9.Legion - A GETH IS NEEDED. Legion is really popular with the fanbase.
That's like 9 already, Casey Hudson did say that in the last game 12 was abit too much so they might reduce the number of squadmates in ME3, but with deeper relationships and interactions. I'd say we'll probably get around 9 or 10 members for ME3..
If it's 10, I'm HOPING we get a batarian. I really want a new alien race to be a squadmember in me3, and after looking through all the available races, the only race which is appropriate combat wise is a batarian, and they will play an important role in ME3 too, along with the other races.
The only other race which we currently have no info about is the Raloi, and I don't think the yahgs are getting involved with council/alliance matters even when the galaxy is at the brink of reaper destruction. (honestly, geez.)
Urgh, I need a BROTARIAN
