I doubt this will be the case given the poor offering on the Force Awakens Blu-Ray. I did not bother to buy it I contemplated getting the later repackaged version with the supposed Chewie ripping off the arms if Unkar Plutt or whatever his name is but it was cut short just like they did for escaping Maz Katana’s castle.
The full scene is on the blu-ray. It was the promo material, prior to the 3d blu-ray’s release that had the scene cut before chewie rips his arm off.
