Yeah, that still kind of bums me out, he'd make a great addition to the cast. But hey, if weirdos like Honey Queen, Wiggler and Metal Mario can make the cut, there's still hope for Kamek.
Anybody else kind of feel like Lakitu is there in place of E. Gadd? They have vaguely similar character designs and a nerdy personality. I really am ambivalent on E. Gadd... if he comes back in something, cool, if not... that's okay too. Though it would be strange if he didn't return for Luigi's Mansion 2.
