This is definitely last minute so forgive me for being late with these thoughts, but this is something that has been on my mind since the day I saw the original cage design.
The Red Cage is meant to:
-Create mounting points
-Give it's operators/handlers a place to grab onto
But in its practicality, it only works for mounting points, and added protection at the cost of added weight.
With all due respect to Matt Tremblay, I think he has it all wrong with his statement on wanting to, "evolve the way cinematographer's ineract with their camera".
He explains that there are two ways to handle a camera being the top handle and the pan/tilt bar of the head. Further he explains that you can also pan and tilt with the Red Cage handles, and they allow for an operator to operate from the front of the camera as well.
Well, the only way a camera op. operates a camera when on sticks & head is with the one and only pan/tilt bar. There is no reason to operate the camera with the cage handles, nor will there be a reason to in the future.
The pan and tilt bar is the direct connection to the tripod head and allows for the most control and manageability of any handling option. So for controlling the camera when on a tripod head, the cage handles are useless.
Are the cage handles usefull for handheld work? No, that's what the front end grip handles are for.
The thing that the cage handles do well though is first off, they create mounting points for the EVF/LCD, which I love, and secondly, give the camera a bit more protection when being handled by AC's and Grips.
If your AC or Grips are handling the camera so poorly that they need a roll cage on the camera, that is just plain sad and they don't deserve their job. Considering that the cage handles add a couple lbs. of weight to the cage, they are in my opinion, (in their current state of design) dead weight.
Now for the solution.....
Let's take the cage's strong points and build on that modularity and flexibility.
Create cage handles that add an abundace of mounting points, give the camera a bit of protection, and cut down on weight in comparison with the current design.
The new handles could be as simple and practical as flat aluminum bent to a half-moon shape with 1/4 20 holes. This will not only cut down on weight drastiacally, but still retain the mounting points, act as handles and add a sort of roll cage like protection for the Red One.
As for the new handgrip cage handles, they do even less than the old handles and once again add weight with little to no useability.
The good thing about the new handle is the top mounts. But, thinking modular and flexible once again, let's sepserare that top mount and have it be independent of all other pieces. Save weight, save space and allow for more flexibilty.
