"New" model VPI?

I've seen 2nd pivot or dual pivot description. Are these the same and what does that refer to? Thanks 🙏 

Built like the proverbial brick  house. Top plate and removeable arm board are about 1/4" aluminum. The sub chassis is even thicker aluminum. The table has VPI anti vibration feet and the sub chassis is isolated but stiffly. The arm is all new with a removeable head shell and azimuth adjustment and there is of course fine VTA adjustment. The arm tube is ess shaped and different; it’s machined solid aluminum and very dead(no tube like resonances). The warranty is 10 years and it’s intended to be upgradable for 10 years. There are two upgrades planned already including a direct drive.

The version one of the Forever series is $5250 with arm and dust cover. Interestingly the parts will fit an original HW-19 base.

I forgot to add, it's a gimble tone arm not a unipivot. 

P.S. It will be available without an arm also.

@dynamiclinearity...you state below that the new tonearm has a "removable" headshell? The pictures I’ve seen shows that’s not the case. Also, how do you know that the new parts can be used on the HW-19 series? Just curious.

I found this:

"The new 10″ VPI S-Tonearm is made from a solid chunk of aluminum, no tube here, and has a fixed headshell. The upcoming Model Two Turntable will include a new arm with a detachable headshell which gets us back to the Modular Design approach of the Forever Series—owners of a Model One can swap out their arm module for the upcoming Model Two or Model Three arm for an easy upgrade. The same goes for the Motor Drive and Platter Module. Nice!"
