I dont know if its been posted before but according to gamesradar the wii wont come with dvd playback...
"Friday 8 September 2006
The Wii console will not support DVD playback when it launches later this year, according to Nintendo's official site. This comes despite DVD playback previously being listed as a feature of the new console. But, in all fairness, does anybody care?"
It doesnt bother me to much but would still be more convenient with dvd playback
