well at least Nintendo GameCube is still popular and in good shape... has a bunch of good techogoly like the wireless controller "wavebird" and mini discs...and the LCD screen...etc.
Most people proably already have DVD players so i don't think there's really a reason for the gamecube to have a DVD player since PS2 was lauched out first and had a DVD player so most ppl have a PS2 so perhas Nintendo don't need to do the same like Sony did lol just my opinon anyway
I believe that Nintendo's next system will still play discs, but hopefully it will play gamecube discs, as well. like PS2 plays the orginal Playstation games
