If anyone else wanted to make them like this, they could have been doing it since before 1950 ... apparently no one wants to make these or if they are, its such a small market we don't know about it.
I suspect what killed it is advances in reliability for tracks for tracked vehicles. In years past tracks of all types were not as good as they are now. It looks like rotating cylinders would be either dramatically taller or dramatically wider than a similarly able tracked vehicle. Tracks with studs would probably work better than the cylinders on slick ice.
One advantage I see of the rotating cylinder vehicle ... the cylinders could double as pontoons for safety on thin ice.
The depression and war ate up all kinds of good ideas and gave us other stuff we did not imagine to replace many of them.
