I initially thought it had a new weapon, but it is exactly the same... the top part is folded out on the new JP one, but folded up with the other two.
A bit disappointing, as the other Deluxe JP figures had new weapons.
Actually, more disappointing was the new weapons for Starscream. He has two massive axes, but can't hold onto them as the hands were too thin for a fist hole. So they plug into the arms like arm cannons, but the massive axe blades stick out, and add nothing to either mode except ruining the look of the "cannons".
