Delayed Wii Production Expansion: http://www.digitimes.com/systems/a20070816PD217.html
Sorry if it's a dupe, but I've looked around and didn't find any thread on this
In short, inability for components production to keep up with demand.
I am a PC gamer, and also have a NDS now, but without access to a Nintendo Wii until End of 2007.
Currently playing: Super Smash Brothers Brawl(Wii), Mystery Dungeon: Shiren the Wanderer(DS), Dragon Quest Heroes: Rocket Slime (DS), WiiFit(Wii)
