For all we know, they might be trying to develop an actual Gunhammer for this one. Not sure about how they would would make it fire shells an d ammo out of it, yet they could implement a wyvern fire mechanic into the super pound like they did with the slam attack of the Gunlance in MHP3rd. Another thing is that the wyvern blast could be element based so you would get a "wyvern lightning" or a "wyvern ice" blast instead of the typical fire element.
