Nerf Mods + Reviews have it up too- a mysterious Swarmfire looking blaster but streamlined to 10 rounds and as a pistol. I'll throw down a "it's legit" mainly on the grounds the photo of the unit has "Not for sale" etched into the side of the blaster.. sorta doesn't make sense to be etching that into a fake, don't you think?:)
I'm sure we'll find out more over the following months, but my initial responses is the blaster looks kinda ugly. While the Swarmfire seemed to make lots of sense in design and functionality, this looks sort of rushed and an ergonomic fail as a pistol style blaster given the size and probably weight. Or perhaps they're going after a more "submachine gun" plan for it.
