**Update**
It will be the pearlized Vivid at 4000 abralon. Should be a nice addition for those who struggle to get the Vivid downlane.
******Now back to your regularly scheduled programs*******
Without having privvy yet to any "inside" info, I would say it is a pearlized Vivid with a 4000 surface instead of the factory 1500 reacta-shine.
I myself have always thought the VG Nano Pearl would have been a big mover if Storm had released it at 4000 instead of polished. The masses (non BR readers) seem to not touch surfaces but throw balls at box finish. The ones who did think the Nano Pearl was too squirty, usually loved it when I knocked the shine down on it.
