It was already noted that the SDCC Devastator was only being sold at the Brisbane convention (instead of both Brisbane and Sydney)... and now we have some extra details from Hasbro Australia.

At the Brisbane show (September 19-20 - Convention Centre), a very limited number will be sold at the Mr Toys Toyworld booth, but a price has not been made public yet.
I would expect at least AU$300, based on the ToysRUs pricing of the regular version, the limited number, and that Toyworld is one of the more expensive retail toy sources in Australia (due to being a franchise).

There are still no guests listed that I recognise as Transformers related, but they do have some interesting Sci-Fi - Fantasy guests if you want to go to see if you can get one of the SDCC Devastators. Start up a meet topic if you want to meet up other members while you are there, as there will be Transformers toys on sale by some of the regular Dealers, plus fan-artist MilesPrower.


(since there aren't any Transformers guests, and I already bought the SDCC Devastator, I have no interest in going)
