Here's my take (assuming everybody survived in ME2): Zaeed, being the selfish bastard he is, would no longer be on your squad in ME3, as he's off hunting down Vido or busy enjoying retirement. Thane would've most likely died of his Kepral's, and Kolyat would be a possible replacement. Samara may be on your squad in ME3 (it's 50-50 due to her oath, and we'll see if she renews it), or being a justicar, she will hunt you down if you're a renegade. Everybody else will most likely be on your squad, especially Miranda and Jacob, who basically have nowhere else to go (if you blew up the collector base). Not so certain about Jack though. But there will definitely be additions and fresh faces around.

Also, Ashley/Kaidan look very likely to join your squad, and Liara is an uncertainty as she's too caught up with the Shadow Broker BS. Wrex doesn't look likely to be on your squad as he's too busy reuniting the Krogan. And if you destroyed the collector base, the Council might provide you a new Spectre squaddie, and if you preserved the base, Cerberus might provide you with a operative like Miranda (I really want a smart-ass Brit[like Miranda] operative who just can't keep himself from making things go boom and cracking jokes).

Now, for allies. If you let the rachni queen go in ME1, and reprogrammed the geth in ME2, those are very likely going to be your allies. Wrex will definitely be an ally, and he may even lead the krogan against the reapers alongside you. Liara...well, if she's not a squadmate, chances are she's going to be your intel provider.

That's my take. Feel free to dissect it and give me your opinions. One last thing. It would be epic if we got Niftu Cal (a.k.a the Biotic God) on our squad. Or maybe a neurotic female turian biotic who constantly screams at herself. And give us that Brit demo-expert with a great sense of humor.
