Just one guys opinion (one who happens to be a host too, albeit on a MUCH smaller level)....
This guy gets 'it'. He realizes the impact Price has had on television and pop culture, yet is realistic enough to know that in the grand scheme of things, it's 'just' a game show.
The more I read and hear from him, the more I'm convinced CBS didn't blow this choice. He has a LOT of work ahead of him in the next few weeks, memorizing the minute details that make TPIR a difficult show to host, but I'm absolutely sure he'll be fine.
