It would certainly be a nice idea, speaking as someone who often acquires merchandise and likes to festoon her house with it (I must admit I'm not entirely sure about the word "festoon", I just like its seemingly chaotic implications!)
They certainly do
some stuff in terms of promo material that goes out with special editions and is available at the games cons, but I think a lot of us would be interested in official stuff we can realistically get hold of.
I have raised the subject with tptb and will be happy to nag them.
