"Our Darth Maul Premium Format™ Figure captures the highly detailed likeness of Ray Park as the feared Sith. From a tattooed face beneath a crown of thorns, his gleaming yellow eyes pierce onlookers, while his stance - light-up double-bladed lightsaber clenched in hand - is one of absolute power and control.*Wrapped in a fabric costume, the piece begins to exude the grace and intensity of this imposing character.*"
That's from Maul's product page. Unless they've since stated they weren't going to, he should have light up. If he doesn't I'd be hella dissapointed.
I hope you are right, I have it on pre-order too.
