A reader came across an unexpected webpage while visiting the Six Flags Discovery Kingdom website. It looks like a little bit of test programming was left behind, with the page title being “Landing Page Blurbs”, but included in the text blurb for “New for 2019 Features”, it does confirm V2 being renamed after The Flash.
“BATMAN: The Ride may be the headlining act of our newest area but we're also unveiling the reimagined guest-favorite -- THE FLASH: Vertical Velocity. There's no shortage of thrills and excitement in DC UNIVERSE.”
