The 2009 catalogue (63rd edition) was the last to have everything in one book. They made the change to issue two catalogues (one for circulation and one for collector) only starting in 2010 (64th edition).
They issued the 1st edition in January 2010 and the 2nd edition in January 2011. If i recall they had originally had plans to release the 3rd edition this january as you mentioned in your first post but yes, i have noticed too that there is no mention on their site about that book. Its very strange. Perhaps the book was not very popular, especially with the fact that you are now forced to buy two books at $24.95 compared to only two years ago when everything was covered in one book at a price of $19.95.
