These wii titles are being confirmed thick and fast since the announcement of the wii name - Not that im complaining or anything :P
Activision said the following:
Here's a link to the CoD 3 trailer:"Through the eyes of four Allied soldiers, Call of Duty 3 brings players closer to the fury of combat as they fight through the Normandy Breakout, the harrowing offensive that liberated Paris and changed the fate of the world. Developed by Treyarch, Call of Duty 3 is the follow up to the #1 next-generation game and is scheduled for a 2006 release."
There was no confirmation that the title would be making an appearance at E3.. but i guess they didnt deny it either.. so who knows.
