Mass Effect 3 Predictions (Spoilers)

Obviously, making predictions on ME3 will involve ME1 and ME2 Spoilers, so fair warning.

1) If you saved the Rachni Queen, they will join the war on your side.

2) Corporal Toombs and his Merc squad, from your ME2 email if you saved him, will likely turn up at some point as antagonists. Possibly as allies if you're given a diplomatic dialog option.

3) If you urged the Quarians not to go to war, and kept both Tali and Legion loyal in their little...disagreement...then both the Quarian and Geth fleets will be available for your side in the war.

4) The Batarian terrorist from X57 will be back, if you didn't kill him off. You'll also hear from his deputy again if you let him go in ME1.

5) We'll find out what Salarian recordkeeping Aria could not outlive.

6) The Terra Firma party will make another appearance.

7) There will be varying consequences regarding Citadel politics depending on how you resolved Thane's loyalty mission and whether the candidate lived.

8) Another Dantius sister will turn up somewhere in the storyline.

9) We'll see the Consort again.

10) Whether we saved Captain Kirrahe on Virmire will have an effect on Salarian participation in our war.

11) General Septimus will turn up again, and possibly have a bearing on how the Turians respond to our call for aid.

12) I will be disappointed if the Elcor and Volus ambassadors from ME1 do not show up somewhere. We need to know what Din thinks now that humanity got a seat on the council just as he predicted they would. :>

13) Emily Wong has to interview us still from our return in ME2, when she emailed us. We also want to have a chat with Dr. Michel.

14) There will be another preacher somewhere. We had the Hanar preacher on Citadel in ME1, and the Mad Prophet on Omega in ME2, so we'll have another preacher on a soapbox somewhere in ME3.

15) Urz the varen will accompany us on at least one mission, if we befriended him on Tuchanka.

16) Mordin will have to choose whether or not to end the genophage so the Krogan can join the war. If he spared his assistant and backed up the data in his loyalty mission, he'll likely have an easier time of this.

17) If we had Kasumi, whether we convinced her to keep or destroy the graybox will come into play.

18) If we downloaded the Cerberus Agent intel in ME2 and had EDI begin decrypting it, it may enable us to put Cerberus in a difficult position.

19) How we handled Ish and Patriarch will significantly affect the calm or chaos of Omega in ME3. We will almost surely be going back.

20) If you got the dialog option where Samara promised to come if you ever needed her, and did not get her killed in the Suicide Mission, then she'll help you at least once in ME3.

21) If you let Zaeed's enemy escape in ME2, you'll have another crack at him in ME3.
