VPI 3D printed arm mod.

I understand that the 3D arm (which is considered one of the best arms there is), now has a (what is called - very major) upgrade.  I understand there is an additional pivot point on the left side of the arm (so it's now a kind of hybrid - not a uni-pivot arm any more.)  I was told that middle road cartridges sound like an Atlas (hyperbole?) with the new mod.  I understand all 3D's can be modified to the new design for 100 dollars.....wow.
