So, it's well documented that the Lego Catalog is NOT an indicator of retirement.
However i thought I'd share some observations since this is a speculation topic
it was interesting that the 4 new Force Awakens sets in the January catalog pushed out the Poe's Xwing (and only the Poe's Xwing) from the force awakens sets. I do not believe it's going away though as we've seen December seal codes in both the US 48R5 and UK 51S5
The FA constraction sets pushed out the OT constraction sets, which makes sense, but it doesn't mean they're leaving the shelves. However if you like them, i'd say grab some before they announce a third wave. I especially like the 2 packs.
The really odd thing is that there are no Star Wars UCS sets in the January catalog at all. Not sure i've ever seen that. I don't see when the Death Star and Xwing and Ewok Village made their last appearance, but they seem to have been absent from the last 3 at least (January, Late Holiday, and Holiday catalogs). Only the Slave I, Tie Fighter, and Sand Crawler have been in there and that was during the 2 holiday catalogs.
Also of note was that the Tumbler disappeared from Holiday to January, and in fact it's gone.
So the catalog means NOTHING, except when it means something
