it may be that Saitek are scaling back production due to the Rhino X55 being released
^ This.
Also, I hear tell that Saitek are owned by MadKatz and since then the latter have had products made more cheaply, resulting in less sales, so less places stocking them... or something along those lines.
Madcatz bought saitek in 2007, 2014 is a bit of a delayed reaction to suddenly have all the big etailers run out of stock if it was a technical issue, the x55 being imminent seems more plausible
