I haven't heard anything about Mytees Bentley wand after the show. They did redesign the head and the manifold was moved.
The joy stick was not completed and was actually made by one of those 3 D printers from Home Depot. It did break but it was not the final product. I have heard this was JUST a PREVIEW of the wand to see what guys said about it.
The handle/trigger I believe does have some potential, but also comes with its own unique problems when trying to use it, It will help with wrist problems but it is kinda hard to not pull trigger for dry strokes, and when you reach for the grab handle it puts wrist in a bind, but they maybe working on those issues now.
The swivel design is without a doubt built heavier duty than there earlier model, I would think the two piece head allows them to set swivel in it position,my guess is some sort or snap ring or C clip is on the Ti Tube adapter and when head is bolted together it locks it all into place. I think this newer design will out last there older version.
Mytee went with a ALL Stainless Steel CAST HEAD...like PC Quad and we all know how good the PC Quad head is right as far as pure toughness goes you could beat through your van wall if need be with the PC 4
So I think Mytee was trying to go in the right direction with that idea, but it made the wand VERY VERY heavy. The wands weight also transfers that back up to the handle and thus makes you notice the bind in your wrist as you go for the grab handle, and also not being able to let go of the trigger, the weight of the wand makes you have to grab on to it.
In all honesty that was really the biggest issue was the weight, if the weight was reduced the wand would be much easier to handle and some of the issues will go away.
OH as far as the rivets, those I believe are removable rub guards, so baseboards, or what ever you edge against has a softer surface and reduces the chances of the wand leaving marks on them.
