Yeah, logically it's hard to see Vader NOT being the one to personally hunt down the Jedi, I mean, what else is he doing all that time? Paperwork? I like the design of The Inquisitor and all but he seems better suited as a henchman and not the lead bad guy. The double bladed light saber seems a little much too. Something less overtly Sithy would have been cooler I think.
It's fertile storytelling ground to be sure though...
$10 says that lightsaber spins around the handle like the Darth Maul accessory and Hasbro will making a toy version.
