Chuck Creators Tease "Game-Changing" Finale

As if their recent all-3-D episode wasn't exciting enough, Chuck creators Josh Schwartz and Chris Fedak hinted at big twists in the show's finale and next season.
Schwartz said the end of the season would be "game changing" for Chuck and his crew.
"We're going to launch the show in a really exciting direction next year. We designed our season heading toward it," said Schwartz.
Though Schwartz and Fedak wouldn't spill any further details, they did reveal that Chuck's ex-flame, played by Jordana Brewster, is filming a new episode.
With Chuck's old flame returning, TVGuide.com asked resident hottie Yvonne Strahovski if her character, Sarah, would also get a new romance.
"Actually, Sarah gets something... something... some candy soon," Strahovski hinted.
What do you think Chuck's new direction will be next year?
