Razer raiju controller for ps4 not available anywhere, does anyone know why?

I searched for a long time, but couldn't find the controller anywhere else, just used it. The controller doesn't even exist on the razer website. Today I came across the controller with an old Amazon link, but it says that it is temporarily not available. Does anyone know why and how long it can take until it is available again?

PS: I mean the standard version, not tournament or ultimate

I guess since it is not on Razer's website that it is no longer produced and is also sold out on Amazon and will no longer be replenished.

But is only a guess, nothing can prove to you.
