As I said in the ME3 article talk page, it could be that cutscenes could depend on which class you are, as well as how the opening sequence of the game may play out, assuming they're going to brink back another round of character customization like they did with ME2. As for squadmates, they could do what they did with Wrex, as in replace them for others. Wreav replaces Wrex if he dies. So in that case, they could have Kolyat replacing Thane, Wreav replacing Wrex, Oriana replacing Miranda, and so on.
