Does Mattel have the 6″ Michael Keaton Batman rights?

So I came across this exchange on Twitter:

If that’s true, then is Mattel withholding a Movie Masters Keaton Batman simply out of spite? Or will we finally see one at San Diego Comic Con (if not sooner) this year?

When the Nolan Batman films came out, they more or less made me forget about the Burton films. But in the years since The Dark Knight, I’ve come to remember how much I loved the Burton films as a kid. All the talk at the time was about how dark and moody they were, but compared to The Dark Knight they’re flat-out fun. And you will never convince me that the Tumbler is cooler than the Burton Batmobile. Nothing on this earth is cooler than the Burton Batmobile. James Dean and Jack Kerouac reciting “Howl” at the Cavern Club while Thriller-era Michael Jackson dances in the background is not half as cool as the Burton Batmobile.

Anyway, those with a Keaton Batman jonesing who can’t drop the cash on the Hot Toys version can enjoy the far-cheaper and yet still incredibly awesome NECA 18″ figure, due this August.
