Are Yonex’ Voltric, Duora and Nanoray series on their way out?

General Yonex question here. Am I right in my understanding that Voltric, Duora and Nanoray are about to be phased out? Looks to me like:

Voltric => Astrox
Nanoray => Nanoflare
Duora => Arcsaber for the balance, dropping the two-sidedness altogether as it was a bad idea from the get-go

Am I right about the above stated assumptions? Thanks for your input!
