I don't know about the Wiki. I've also heard that Icon or someone is offering one that "transitions."
I've heard that one isn't very good.
The one on the Akuma is the trademarked, Transitions lens, just like the sunglasses. I love it, works great.
They are coming out with visors that have a button that INSTANTLY changes from clear to tint also; not for sale yet. Operates off of a very small battery near the pivot point with integrated button. This would be great for entering tunnels for example. But for now, you can't beat the real Transitions visor. And I bought a spare, but got the other one that transitions...from clear to mirror.
