Looks like another short run Ruger firearm to me.
Why not a 3" 9mm, 40 or 10mm GP100?
I saw the Super Redhawk in my last American Rifleman.
Seems pointless to me.
You must be referring to the 10mm wheelie already discussed & debated extensively here:

As far as Ruger chambering the 10mm AUTO in/on a particular a frame-size, ... yeah, they could've done it easily on the standard RedHawk, just like they did with the .41Magnum RedHawk, and there wouldn't have been any issues. And yes, the GP-100 frame was do-able too. In its maximum loadings, the 10mm just begins to tread into the fps/fpe specs of
low-end .41 Mag loads.
That said, the 10mm SRH - for those that get one - will most likely serve as the base- or doner-gun for "conversion" to
10mm Magnum by having the cylinder chambers reamed out to Magnum specs, a not uncommon practice among S&W 610 owners, especially those with the 6.5" model. It's a job most competent revolver-smiths can do in their sleep (Hamilton Bowen being one name associated with this conversion).
One immediate utility of the conversion is the ability to use the same moon clips to load and shoot .40S&W, 10mm AUTO,
and 10mm Mag cartridges all from the same gun - 3-in-1 fun.
