Sorry, will update it more very soon... but here is a little until the official story...
Ha - there are some new Gladiators - but between family, work, and other events, I have not gone to a taping (they are being filmed at the Sports Arena in Los Angeles NOW). And I do know a lot, but not fair to reveal stuff
Seven new Gladiators include Jet (female winner from last season), Pheonix (female with pink hair), Panther (female), Steel (female), Hurricane (male with pink, blond and black hair), Zen (female), and Rocket (male)..
And yes, Siren and Venom, Justice and Wolf are still there, and competing.
New events include Tilt, Atlasphere, Vertigo, Rocketball, Snapback, Skytrack...
