I think the "Bling" after the name of the gun is some sort of customization, not necessarily Golden Guns. For example, we see "Bling" after the name of a gun twice, once on a SCAR-H/ mk16 (The gun used at the beginning) that is lying on the floor, and on a Styer AUG-HBAR also lying on the floor. Then, later in the video, more additional info after Gun Names shows up. At 1:06 in the Video, a TAR-21 (Israeli Bull-pup Rifle) briefly shows up with the letters "FMJ" at the end. A few seconds earlier than that, a H&K UMP45 shows up with the words "Extended Mags" at the end.
So I guess we have a much broader customization ability coming our way on 11|10|09!!!
