Interesting ideas, though I didn't read everybodies. One idea I've had is that The Illusive Man could be indoctronated. He seemed extreamly angry that the Reaper tech was destroyed, or pleased that it was saved. Meaning the Reapers could be controlling him.

As for the squadmates, I can see alot of them returning, and some not. Garrus, Miranda, Jacob, Grunt, and Samara have the highest probablity of staying. They are all loyal to Shepard, and have no future plans. Thane would also stay with Shepard, but his sickness would probably kill him. Same with Mordin. While he has alot of potential, curing the Genophage ect, Salairians only live to about 40 and Mordin is very close to that. I guess he will die of old age. As for Tali, with her father gone, she may step up to join the admirels to keep her people together. As much as I want Legion to stay, he will most likely lead the Geth against the Reapers. I fear that is you take the paragon path on Zaeed's loyalty mission, let Vido live, he will not be a squadmate. He will probably go off to find Vido again. I could care less about Kasumi and Jack. Both of them are bland and useless characters. I usually go out of my way to kill them both. If you didn't do Samara's loyalty mission, she will probably not stay. She will go after Morith. I can not see Liara coming back as a squadmate. Probably as a supporting character, but nothing else. Ash/Kaiden will probably come back. They will most likely trust Shepard not that the Collecters are destroyed. As much as I like Wrex, he will most likely not come back. He will lead the Krogan against the Reapers.

For New squadmates, I thought of Kal Reegar(if still alive), Cpt. Kerihee(if still alive), and Aria(if you gave her the datapad about the Mercs going after her). Thats all I could think of. I hope there is alot of new characters aswell.

Your past decisions could get you an army in ME3. The Rachni from saving the queen; The Krogan by saving Wrex on Virmire; The Quarians by telling them to stop fighting the Geth; The Geth by rewriting them in Legion's loyalty mission; ect.

That is most of the ideas I've had on ME3.
