Alex Tebek and Pat Sajak in Hi-Def. That's a scary thought, isn't it? Well, if you think it is, then don't bother to watch Jeopardy! and Wheel of Fortune this season, because both will be offered in HD for the first time ever. According to TV Week, the sets of both shows have undergone extensive renovations in preparation, making them wider, more detailed, and more colorful, and episodes for fall have begun to be shot by both King World-distributed shows. Also, the signature J! gameboard of individual video screens has been replaced by a video wall, similar to what's used when the show goes on the road. They are both the first syndicated and first game shows to go HD.I still think they should follow Ken Jennings' suggestion and add physical challenges to J! But that's just a personal preference. Oh, and what are the odds Vanna White had some "work" done in preparation for the more-detailed broadcast this season?
