From the looks of things here are my guesses:
At 0:08- That red one that opened up looks like the equivalent of a Maverick for this blaster.
At 0:10- What's that line near the back? It looks almost like the thing you use to pull the bolt on the Longshot and Vulcan. Also, that round bump on the grey part looks like the motor that spins the disk.
At 0:11- Whats the orange nib on top? Firing control? Motor spin up? Cocking mechanism? Who knows.
At 0:13- If you pause right at the intro you can see more of those red flip opens as well as some other blaster.
At 0:14- In front of where the clip is inserted that looks like a battery pack, but this one is definitely pumped. Does that mean these are mixed electric-spring blasters? Also, that thing looks like the disk launching bastard son of a Recon, a Barricade, and an Alpha Trooper.
At 0:17- You can see those other blasters again here. No idea how many discs will fit into that little one. Also, I just realized how terribly bulky the red one is. The shoulder stocks have some wierd black thing on the end of them, but they're as flimsy as ever.
Also, the voices very clearly say "Vortex Praxis (Practice? It sounded like praxis to me), blaster 1, test shot 1" so at least we know that blasters name, and the hand on the box is clearly holding a handle, so the stampede/raider-esque we saw with the handle is the Nitron.
We should compile a list of possible pros and cons rather than arguing one way or another about it.
-A Clip System with at least one stampedesque clip
-Apparent better stock range
-Thinner = more capacity?
-Bulkier clips by far
-May not be moddable, or may need different mods
-At least one of them is non-clipfed and also not able to be reloaded while still primed
-May be royally effed by wind
-May fly slower
-Are they electric or spring?
-Was that just a lucky shot?
-Is it just me or did his shot veer to the left?
