It looks like there might be an official announcement coming of a Japanese Masterpiece Thundercracker using the new MP-52 Starscream mould (due out in June). According to a teaser image, it looks like something will be announced or revealed in a few days time (January 14th).
If the colours are accurate on the teaser image, it looks to be following the cartoon colouring with a pale blue, rather than a deeper metallic blue of the orignal toy.
