I have a 2002 edition, from when I started collecting about a decade ago. Took a quick check online to find where I could purchase an update, and the most recent I'm seeing is 2009 (and for a price, used, that I'm not willing to pay: $186 via
Amazon, a crazy $366 Buy It Now on
ebay!). Would it be a good guess that it is no longer being published (and that 2009 was the last update)?
