That is the way in the "SonyWorld." The update info doesn't appear on their site (support, drivers/software) for several weeks. Even when they do get the latest information, it's generally cryptic as to what it has accomplished.
So aside from waiting, you usually come away without really knowing what the hey went on.
My 65/900A got an update earlier this week, and the site still shows the 11/20/14 version.
My 65/950B got an update a while back, and the site still shows the 12/3/14 version.
The FMP-X1 doesn't have any information on any past update, although I remember it going through one a year ago.
The FMP-X10 got an update Jan 6, 2015, but that didn't include the Amazon 4K app that is supposed to be coming soon.
End note, don't expect to get current information, or to really cull any reasonable conclusion from what they do finally provide.
Now that's Sony Style!
