For me, Wii connect direct to TV, no noticable delay, so I'd say less than 0.1s.

Of course, various issues in the environment can contribute to delay, including TV set and VGA box design. Some TV sets and VGA boxes are known to have very noticable delay due to poor processing speed. Same thing for video capture cards and computer capture software. Windows MCE is the worst offender, I notice that any input from the tuner card is delayed up to 5 seconds.
