Your link doesn't work for me.
From what I know of the US market, the only company that has the Cherry MX "Silent" switches is the
Corsair STRAFE RGB.
This keyboard isn't out yet, it ships from Amazon in 2 days on Oct 4th. Maybe some other retailers are already shipping though.
According to Corsair's website, these Silent switches are "Exclusive". I don't know if that means they made a deal with Cherry so no one else can have them for a certain period of time, or if they bought the first batch so no one else can get them right now.
Anybody know of any other keyboards that will be getting the Cherry MX Silent treatment?
I found an English
product page that gives the following info-
Noise optimised MX-RGB keyswitch version optimised for use with SMD LEDs (RGB or single colour)
The only solution from a single source: patented (patent pending) noise reduction with integrated 2-component stem and worldwide unique Gold Crosspoint contact technology
Minimises bottom-out and top out noise.
