It's not a surprise but with the Amped coverstock listed I would say that's a pretty clear indication that the No Rules Pearl is coming stateside at some point.
If you're inferring that everything on that chart is released (or will be) domestically, you are mistaken.
MicroSnap
Armor Plus
Armor
NRG Smooth
Are all aging coverstocks that never released stateside. The R3S Pearl was also an exclusive line coverstock that barely made it stateside with the Snap Lock.
As the Snap Lock made it to the states 6 months after Japan released it, who's to say the same won't happen with the No Rules Pearl though?... Europe, Korea, and Japan all got the No Rules Solid and No Rules Pearl simultaneously. For being Made In USA, it's a shame they would give us "sloppy 2nds" months later instead of offering us more, higher developed versions #MilkingTheCow
