I assume it still was one, yes, but we've gone through all*
the major characters in the promo/placeholder image
and OP now, so they have to come back or else there's no cast left.
Except deus ex machina-chan up top there. If she's not the crazy game creator's "dead little sister who he can't let go of and programmed into the game" I'll eat my non-existent hat. Though it'd be neat if it weren't something so predictable too. Maybe a variant of it where she's comatose in a hospital somewhere and he made SAO as a world she can move around freely in. Why it would require real death I don't know, but crazy guys are crazy.
