In the future Wii's will be able to play dvd videos, HOWEVER, Nintendo have said in an interview near the launch of the Wii that unfortunately it would require more than a software upgrade. It would require some extra hardware.
Therefore, it will NOT be possible to update your Wii to make it dvd playable.
However, they did say that when the dvd Wii's came out, current Wii owners would recieve a big discount when exchanging their's.
