Where did the GTX 770 go from December Buyer's Guide?

Looking at today's updated buyer's guide, I noticed that all the GTX 770 graphics cards are missing in favor of only the 760 model. Any particular reason why?

The 770 is getting harder and harder to come by (Newegg only has 1 in stock and it's heavily marked up - the rest are all out), and if you're comfortable setting the flags for nVidia's drivers, the 970 is a better choice at that price range.
