Nikon SB-900 speedlight has reached end of life?

I received separate emails from retailers in two different European countries that the Nikon SB 900 speedlight has reached end of life and can no longer be ordered. This is a rather unusual development since the SB-900 was announced in 2008. The previous SB-800 model was announced in 2003. Maybe this is just a glitch in Nikon’s ordering system.
