Nintendo wasn't exactly all that specific when it recently warned of possible Wii shortages through the 2007 holiday season, but it seems that some component makers now have a bit more to say about the matter, and they're claiming that tight supply of IC chips, PCBs and other parts has forced Nintendo to delay its plans to expand production. According to DigiTimes, that would make any easing of Wii shortages in the second half of 2007 'unlikely," although we're guessing that they'll still be a fair bit easier to come by than they were last holiday season.
