Apparently somone snapped a pic of The Flash display where we can see the brighter colored red suit with a white symbol.
Jay Garrick's helmet is also featured, which may mean the character will be appearing in Season 2 as well.
Another possibility is that The Flash suit in this display is just the costume from the future Flash -- seen when Barry went back in time and watched his mother's death.
We'll probably learn more at the WB TV panel on Saturday.
