I also think it's VERY unlikely she will do a PV for an old song. Above all when it's as old as SAKURA or Will. Except Duty which had that Pachinko visual, I don't remember she's ever done it.
Either it's for Pray for you or another new song / cover.
I'll personally be more disappointed if it's the only new PV and it's for an old song. And please, I don't want Shimomura to potentially (and the chances are great that he'll do it haha) ruin the perfect gem that is Will.
