This toy was first revealed around the middle of the year, probably at the mid-year Tokyo toy Fest, but since it was a Movie Megatron toy that didn't appear to be much different to the 2012 Dark Energon Megatron toy, and wasn't a deco that appeared in anything Movie-releated, it didn't generate much interest.

As such, we went past it's original release date last month and I didn't even realise that it had been delayed to the end of November.

It is one of many TakaraTomyMall exclusives lately, and the official images can be seen here... while the first in-hand image (of it in box) can be seen here.
It isn't a clear photo so far, and we'll need to see one out of packaging, but compared to the 2012 version, the box is almost identical, and I couldn't see anything obviously different about the toy.

It was 15,000yen at TakaraTomyMall (about AU$175), which isn't cheap, so maybe the Hasbro Asian units will be less. There are 2000 units being sold by TTM, but there is no idea how many units Hasbro Asia did.
