One of the reasons for this might be because it's price is not that bad. It is CDN $80, which is the equivalent to about USD $60 which is about the same price it cost to initially import those two toys to the US (Granted the Bumblebee mold was also available in the US and this Platinum deco is different to all the previous decos of that mold). If anyone is curious, that Grimlock is long gone from any site offering him and is now only available on e-bay for the price of this whole set. There is no solid evidence indicating where and when this set will be available in the US.
The listing offers us something extra too, some new photos. We can now see the alt mode deco and it seems that Grimlock is not painted black like the Takara version but rather gun metal black/dark grey, with some more grey at certain places making him less show accurate than the original Takara deco.
Well goodbye to my LG Ultra Magnus and United Blurr and an awesome hello and welcome to your your new epic replacements...'nuff said!
