Yes, Lego has officially confirmed that they will be gluing all future magnet sets. This originated with some licensing issues with the licensed lines. My understanding of the situation was that selling individual figs (or fig packs, containing no "building" elements) were considered to be too similar to action figures, and the holders of the licenses didn't want competing products. Making the figs non-playable seems to have placated the license holders. Lego produces all the magnets in the same factory, and it is apparently too much effort to glue the licensed ones but not the non-licensed ones, so all magnet sets will be glued.
I think it's ridiculous, if only because surely the (usual) $15 a pop price could accommodate dropping the gluing step out of the production line for non-licensed magnet sets.
I didn't even realize until just now that this would also naturally encompass the Bricktober figs. Sadness.
In related news, though, TRU also has some 2x4x3 bricks with a Ninjago logo on them, currently. I don't know what promotion they are a part of, but I was able to get one today, when I got my Bricktober fig. It might be worth asking about, if anyone cares.
