This is actually Ubisoft's eight confirmed game for the Nintendo Wii, so I guess by now we can assume that Ubisoft thinks the Wii will be a success, which is great of course.
"We are very excited to bring Tom Clancy's Splinter Cell Double Agent to the Wii this holiday season," said Tony Key, vice president of marketing at Ubisoft. "The Splinter Cell franchise has always translated very well across multiple platforms and we are confident that the Wii version will continue the tradition of maximizing the capabilities of each respective video game console platform."
The game will be based on the Playstation 2 and Gamecube versions, but of course with improved graphics and gameplay mechanics. You will be able to use the wiimote for controlling, but Ubisoft hasn't said anything specific, only that they might include a feature where you shake the wiimote to open locks.
The game will feature a branching storyline with multiple endings, so what you do and say in the game will have an impact on how the story turns out. And you will get Missions from all over the world, from Asia to Africa to the heart of the US.
No multiplayer mode have been announced yet, but Ubisoft confirms that the game might use Wiiconnect24, so you can download content for the game.
Splinter Cell Double Agent is scheduled for release at Wii's launch day, which probably means later this year.
