Nickelodeon uploaded this sneak peek of the show onto YouTube. We see how Marc will be involved with the show, and new physical challenges. It seems they're moving away from the super messes of the

Family, and
Double Dare 2000 runs, and embracing the teamwork aspect of the show-in the contestants and in Liza and Marc having good banter with each other. Marc is seen describing the physical challenges and tossups, to balance out Liza's hosting of the game.
Also, it appears that the dollar amounts are updated to account for inflation: $50 for the tossup and $50/100/200 for questions in Round 1, with $200 physical challenges. Double the dollar values for Round 2 and we have $100 tossups, $100/200/400 for questions and $400 physical challenges. These are the highest dollar values for the main game in the show's history.
I like how they kept the original show's 1986 aesthetics and soundtrack, and updated both for 2018. This looks to be a great revival of the show, and I can't wait to see it.
