The Night Elves are going to be part of the alliance? I would think they'd be different... even going on the storyline of WC3... since the Horde is obviously on a different side... Wouldn't the alliance be like it's always been, and be Humans, Elves and Dwarfes and not the Night Elves, too?
I haven't really read the official site in-depth yet, so if it says it there then I just didn't know.
