--- I've been thinking, and no matter what happens (as some have touched on already) BioWare kinda boned themselves with this.
If this was all part of a marketing scheme (if the Indoc Theory is true) they pissed off people who are against cutting important plot points and putting them into DLC AND people who found closure and satisfaction in the current finale.
If this is their true overriding artistic vision for the Mass Effect universe, they pissed off all the people who got used to victory against all odds (Read, 99% of the typical Video Gamer.) as well as people who loved the way that they could see the story be shaped in whatever way they played to.
If the ending was rushed and truncated by EA's business practices, then they pissed off everyone who wanted more variety in the endings, everyone who enjoyed the current endings but wanted more clarity, everyone who enjoyed the universe's overall extreme level of polish, and everyone who was just plain enjoying the ride and then found that it was over.
Or if the ending really IS as complex and layered as they say it is, and we all don't understand, then BioWare has pissed off everyone who, until now, felt smart and who probably really IS smart (Playing Mass Effect through the first 2 games makes you twice as smart as most people I know) but who now feel stupid and confused.
BioWare needs to whip out a real-life Deus Ex Machina, go back in time, and delay the game's release another 8 months to make it as incredible in EVERY way as they wanted it to be.
--- Oh, and (SIDE GRIPE!) to give us a fight where we're there not only with 2 squadmates, but with every surviving ally we have. I mean EVERYONE. Kaiden (or Ashley) Garrus, Wrex, Tali, Liara, Miranda, Jacob, Jack, Zaeed, Kasumi, Grunt, Samara, James, Edi, Joker in an ATLAS, Kolyat, Primarch Victus, Anderson, Hackett, any of the soldiers we walked past and overheard on the Citadel, OTHER SPECTERS (For being such a powerful force, we see far too little of them,) Bailey, Aria T'loak, Liara's "dad," a fistful of Geth and Rachni, Kenn (the traumatized Quarrian from the first ME2 mission,) the quarrian voiced by Claudia Black (Admiral Xen, was her name?) and anyone else I can't remember. That would have been badass. just a big effing battle royale against a few hundred reaper ground forces. Would be cool to even have it where if someone bites it in that fight, based ENTIRELY on performance, they're dead dead, not just knocked out until you use first aid.
Siiiiiiiiiiigh.
