There's a new variation shown of there @ rebelscum that is a basic Ani with a Dooku lightsaber
I just took a look at the picture and by bs-dectector went off...
If the toy came with a hand molded with a Dooku lightsaber in it THEN I would be convinced. However, the left hand can not hold anything and the Dooku lightsaber is just a lightsaber (i.e. no hand molded to it) so there's no way to have the Anakin figure hold BOTH sabers like he does in the movie.
If the figure came with a flesh hand molded with the Dooku lightsaber and you could put that hand on Anakin's left arm then YES it would definitely be a variant.
As it stands now this looks like someone bought both Dooku and Anakin and then put the Dooku lightsaber into the Anakin package.
