I think we had a discussion on MP Grimlock redeco options (Gen2 colour, and maybe Overkill, but that one's unlikely as the Classics Overkill was already pushing it), but I agree that there probably isn't anything they can do with Megatron - and it's inability to be released by Hasbro proabably makes it non-profitable mould (justifying the excessive redeco-ing of other MP moulds to make up its losses).
