That's if they even make Nigo. When was the last time a not-Ichigou Showa rider got a collectible? Gaim, 5 years ago, and that was a big Premium Bandai Exclusive. That's even happened to all the Heisei Riders recently, come to think of it.

EDIT- Okay, I forgot the "Ridoron" Shift Car that got released, but even then, that was probably only released for the fact it was a car.
