Yesterday, the official Facebook page for SSX tossed up that splash image, and the deliberately-worded caption underneath sounds very much like SSX Tricky has a hand in the snowboarding title's upcoming DLC release.
"SSX fans have shown their love for the game's rich history," the game's makers said. "We love that history as well, and that's why we're excited to be bringing some classic elements to the newest SSX release in our upcoming DLC release. We'll be letting you know more on Monday, but for now we're off to launch some fireworks in celebration."
As commenter DocSeuss points out "That's Elise in her Tricky outfit!". That, plus the fireworks and lights, signals that the PS2/GameCube/Xbox hit is on its way back, in some form. Stay tuned.
