The Stampede is an Assault rifle class, being just over 75cm long, just about the same size as an actual carbined M4 with it's stock retracted. The 18 dart clip is another point. It is more the equivalent of an assault rifle in most aspects, the blast shield and Bipod combined with a 35-dart clip is as close as current to an LMG it can get.

No chance of the Cerberus being released. I sincerely doubt they could possibly make a 12 ammo-cap rocket dart gun, be lucky to get two. All is not lost however, they may use the design for a future nerf gun, albeit using an actual clip system or possibly use the old reactor balls as ammo.
