They've raised the bar for television so high that very few will even try to match it.

Happily, I've heard rumors of a new show featuring the "Build Team" of Kari, Grant and Tori. I saw a clip a few weeks ago of Imahara spilling the beans about the three of them hosting a "Mythbusters-like" program.

Adam Savage always seems to have things going on, especially on the internet, and I'd guess that he'll continue to be a fixture at major conventions and gatherings for years to come. Jamie, OTOH, seems like he'll have no regrets at all about relinquishing his celebrity (though he'll always be a rock star in the fx biz).
