I'd imagine they will release Thundercracker, but probably not for a year or so. I'm rather torn over this, I am a fan of Skywarp he was my first seeker and all so its tempting. However I do prefer the realisim of the Takara MP line just a little more, so If I want cartoon colours I have my Classics.
Still maybe somone other than Toys r Us will get him, and he'll be cheap.
