Changing topics, now.
Who do you think the unidentified Male sniper (from the reveal trailer) is? Is he an unnamed civilian simply used to showcase the devastation brought forth by the Reapers, and how Shepard is the hero that everyone is looking for?
Is he a specific character that we may have heard of or seen before?
Maybe a potential squadmate for ME3?
I don't think he's a civilian, mainly because he's been dosing himself on stims / painkillers to keep himself going from his leg wound that was bandaged up. Seems like local Earth military, probably an Alliance marine that was in the middle of London when the excrement hit the circular rotating ventilation object.
I'm sure Shepard's looked in two ways in regards to the Reapers. One side looks at him/her as our savior and the only one that can defend Earth and the rest of the galaxy against them. The other side looks at him/her as the person who stirred up the beehive of the Reapers and that we wouldn't have had any issues without what he's/she's done against them.
Second group is obviously batshit crazy to have their opinion.
Someone mentioned in the leak thread that the person with the sniper rifle is Grayson, which I'm assuming is from one of the books. Not sure of the reference otherwise.
I'm sure if he's someone that's been brought up in the books and Bioware considers them to be canon, he could be a squadmate or NPC.
