I agree, with all the squadmates in ME2, BioWare pretty much screwed themselves for bringing any of them back for any major roles ME3 in my opinion. Unless ME3 is going to be twice the size of ME2, there are way too many variables for ME3.
I would even be hard pressed to think any of those people who had ME2 romances to have them back in ME3 (what are there, six romances?) there would have to a lot of individual dialogue for each character, it would take up memory in the disks.
Even the math doesn't make any sense, you have 11 squadmates, anyone one of them could have died, anyone of them could have survived, they all could have died, or they all could have lived, what are they all going to be doing in ME3? Besides a cameo.
There is just way too much information to fit onto a disk unless BioWare really wants to and makes ME3 longer.
It is unfortunate, some of them are interesting (not you Jacob, sorry Jacob fans, I love to take a shot at him, lol) but it might very well turn out to be true.
I am honestly at a loss for ME3, what can BioWare even do after the ME2 storyline?
Depending on who died, if TIM got the base amongst other choices should change ME3 completely. BioWare may have dug themselves into a hole trying to do the over the top style of ME2. There are many decisions that would change the fate of the galaxy in ME3 during the Reaper invasion.
I don't know, maybe BioWare is going to make ME3 a 100 hours, it is the only choice they have after ME2.
Otherwise they would have to do some sort of ending where there are only two real endings but they barely change depending on what you did. Kind of like pre-DLC Fallout 3.
Maybe Mac is actually a genius and he can bring it around or Drew will come back.
At this point, I am strongly hoping it wasn't his decision for the way ME2 turned out.
If someone higher up in the company wanted a "dark" storyline, who is he to say no? Might be wishful thinking on my part.
There are still ways to bring the ME2 storyline around in time for ME3, it just depends on if everyone at BioWare wants to do their best and have ME3 be what it truly should be.
It isn't that hard to address some of the major concerns with ME2 (Liara reunion and such), they could even greatly expand the ME2 storyline with a gigantic Liara expansion. They could turn the expansion into a compelling storyline set after ME2, I mean the Reapers are coming, the SB is apparently involved, Liara is involved, Cerberus is involved, and the Alliance is in there somewhere. The writers should be able to come up with something great if someone told them to do it.
Hell, I can only write well for academic/science papers and I could probably come up with something using those ideas.
Funnily enough, BioWare could address all of the ME1 LI concerns, create a better ME2 storyline, give us Liara back (the best part

), and more with one expansion about Liara.
