Now that 40K 8E is out, it's not surprising that they're using it for the core mechanics with suitable mods and chrome added on. Not a horrible set of rules, and the biggest complaints I've heard all revolve around vehicles - which should be a non-issue in Necromunda. The models look nice, and it sounds like probably all six of the original core gangs will be returning initially, followed by the farther-out stuff in Outlanders.
Have to wonder about that last line. "Juices" are a typo or renamed juves, maybe? Make sense if they needed friendlies nearby to avoid dithering.
Brightest point of this for me is I'd call it proof that we can expect Battlefleet Gothic to relaunch eventually, and the models will be amazing.
