Given that Fremantle can air hundreds, heck, thousands of game show episodes where Johnny announces across Buzzr/Barker Era Price, I don't think that's a concern.
But personally, as great as Johnny was, I'm not tuning in to the show now to listen to him or Bob. I'm here for Drew and George now, and it's unfair to George to have to yield to an old clip recording every time they want to play this game this season.
And speaking of this season, I'm glad this is a one-season-and-done game. It's fine, but we're simply playing Cliff with an easier range because the subject material is harder. I'm also not necessarily sold on the idea of playing a pricing game which requires zero knowledge of current, present day prizes and the like (someone could likely counter that Now....or Then is also like this but that is incorrect; you can know the prices of everything "NOW" and know that the prices that don't match are "THEN"s).
