What games are confirmed so far? Duel, The Wall, Powerball and obviously The Eliminator?

Those you've listed plus Hang Tough and Gauntlet from the original series (looking at the trailer Gauntlet appears to be 4 Gladiators compared to 5 in the ITV series) plus 3 new games - The Edge (not sure what this entails), The Ring (looks a bit like Pyramid but flattened i.e. Contenders trying to get to a button in the middle of the floor with a Gladiator trying to stop them), and Collision (think Hit and Run but with the Gladiators themselves as the projectiles rather than demolition balls).

The Eliminator itself looks like the classic version rather than a reimagined version.
