Hasbro Asia is pretty good with having catalogue booklets for Transformers (both times I was in Hong Kong, the ToysRUs store had free copies for people to take), and a new one has surfaced in Taiwan... covering most of the 2015 toys (Combiner Wars, RID, Rescue Bots, Kreo) and the first wave of 2016 Combiner Wars. Plus, some mini bios for the 2015 RID Minicons and Deployers.

I don't know why (western) Hasbro branches don't release these (in the applicable languages), as they are a great thing for kids and collectors to have as a physical copy of the toys they might want, or as a reminder to hunt down.
I don't think I would have been as passionate about Transformers 30 years ago if it wasn't for the Gen1 catalogues that were in the boxed toys, that I would spend unbelievable amount of time studying and dreaming about owning one day.
