Demolisher 2-in-1

So, we've had a ton of speculation surrounding the upcoming Demolisher 2-in-1, depicted below.

What we have here looks from the right to be a crossover of Rayven CS-18, Longshot CS-6, and Stryfe CS-6.
Rayven, because we can see a top rail and a side rail.
Longshot, because it comes with an under-barrel cannon.  (Hopefully with better range than the dud that came with the LS)
Stryfe, because it has a detachable stock, flywheels, and the flywheel blaster mag-release button.

We were hoping that the rail on the right would be mirrored by one on the left, but no such luck, as seen below.

And the under-slung grenade launcher, to quote Adult Fans of Nerf, (Above image kudos to them) "does not come off, just like it appears in the pictures we’ve seen. It also sounds like it gets pretty decent ranges despite having a very simple method of operation. When you push the slide forward it primes the launcher and it launches on the pull back."

This monster looks to be about as front-heavy as a rapidstrike, but much more compact.  Still, it's only semi-auto, which ruins the M4-aspect a little.  Good news: There's ~8 months until this drops, and this has already "changed 3 times in the last 6 months", to quote UK Nerf.
(Enough time for them to make this full-auto, and make the banana magazine hold 20-rounds!)

Utility-wise, the stock is a good idea, but looks like the 'nade will get in the way, and easily fall out.  Either a Raider-class stock or a Spectre stock would be quite efficient, or if you wanted extra ammo, a Recon stock.

Also, the tac-rail on top seems too far forward for comfort, but we'll have to delay judgement until this drops.

I love the barrel-extension port, and the under-slung 'nade launcher, and am waiting for when this is released.
