In an email from altus to GoNintendo they released this statement:

First off, Trauma Center: Second Opinion is definitely a launch title for the Wii in North America. That news right there should make a lot of fans happy.

Now for those nasty “straight port” rumors. Trauma Center: Second Opinion, while it stems from the DS version, will feature a massive amount of new goodies. Another playable character, new surgical tools and situations, obviously new graphics, and of course, full Wiimote utilization.

TC:SO is sure to use the Wiimote to it’s fullest extent.

On top of all that, there are more details about the game that haven’t been released to the public as of right now. Finally, the game will be chock full of voiceover work, instead of just the “Doctor!” and other short audio clips you heard in Under the Knife.
