Thanks for letting us know. I'll definitely set this up to watch now. Remind us again right before it airs 
I can confirm you have five seconds to answer the question.As a huge fan of the UK version, which has four contestants and a little less filler, I kinda liked the changes that stop it being a direct copy - namely the chasers. The amounts involved are ginormous in comparison and the individual chase questions are a lot harder (the UK version can see up to 8 or 9 correct answers).
I was intrigued to see that the sound effects during the chaser board were the same, which made me wonder if there was a five second time limit to pressing the answer button like the UK show or not (like the GSN version).
It worked the same way on the UK version of the game, with "The Beast", and I used to gripe about that as well. Sure, it's locked in (we assume and are promised) but I'd rather hear it from the Chaser and know it that way (or see it on the screen if they want to show it that way, just to have it confirmed in some way that makes it more obvious what they chose).I thought the snarky comments from the peanut gallery was a little odd.
I also would have liked to see the Chaser give his answers before the answer is revealed. It's a little weird when they go "oh, yeah, I got that one right." I know he certainly had the answer locked in, but it still kind of feels like he could just say he got it right when he really didn't.
