Some preliminary videos coming out from SHOT.
This one was the best, I've cut to the point where he's actually racking and shooting the shotgun, as we've already covered the features and price:

The pump action looks notably smoother then what we've seen with the KSG; it looks comparably smooth and easy to a normal 500/870 action. So the risk of short stroking seems greatly mitigated / eliminated.
Recoil, however, is brisk, as might be expected from a 5.9lb 12 gauge.
