I've watched all the trailers and I can't wait to see the show! They've got a great selection of guys hosting the show (not hard to look at either...) that make nerdy stuff more interesting than I thought possible... good stuff... !
My favorite is Terry Sandin, he's got a sense of humor that makes the show unique. All of the guy bring their unique brand of nerd to the table... but Terry (and his laugh, and silly dance) are my favorite. It's about time Discovery did a new "reality" show myth-busters style with a decent cast and premise... Smash Labs was simply sad in comparison. Looking forward to the first season of Prototype This!
