Code Red SP was another Solid along the Black Limited and Blue SP... it had the R3S Solid (1500 polished) released in 2015
Great majority of the Codes are pearlized and remakes (just different color/scent)
There was a leak of a Code Perfect (R2S Hybrid) a few weeks back... I would think that's next to release overseas.
As for USA, it is confirmed more Codes will come (and not all of them from overseas). Would rather see a brand new one over a remake played off as new.
... Nano Lock would be interesting to see released in the states. It took Storm a few years to bring the R3S Pearl here (Snap Lock). The Nano Lock has the NRG Smooth cover (notable NRG Smooth releases: Marvel Maxx [original, 2, and Gold], Virtual Gravity N/S, and Wild Bite Extreme). The NRG Smooth cover is very impressive... I would describe it as a urethane motion but with enough strength to cover the boards of reactive pieces.
I'm more curious about what (and who's) signature line release is coming after the Timeless?? Osku! lol
