^Yeah, I've been looking at that, but so far (short of data mining it myself) I can't find any actual proof. As far as I can tell it's all based on one person's word.
Still interesting if true. I'd always thought it'd be fun to have your decisions in the SP campaign reflected in MP, but I could never figure out a good way for them to implement it. I mean what if (like most players I imagine) you have more than one Shepard? Does everyone on the MP team get stuck in one person's person canon for the duration or does everyone experience a slightly different mission?
Nice idea, but I'll believe it when I see it.
