New VPI

I just received my MusicDirect catalog and noticed a new beltless rim drive from VPI. It looks like an "add on" to any VPI table with an outboard flywheel and is standard on the new VPI Reference Super Scoutmaster TT.
Is this belt-less approach similar to previous approaches to drive the platter? (e.g. idler wheel?)
Any info/guidance would be appreciated.
Thanks
