From the article by Kotaku's Mike Fahey:
"As the holidays season started heating up, things looked bleak for parents and gamers looking to get their hands on Nintendo's tiny, motion-controlled console. Rumors of chip shortages ran rampant, and I personally was certain that the eBay grey market price for the hot gift item would far meet if not surpass the highest numbers seen during the initial late 2006 release window.
Miraculously that never happened. At the very last moment, in a series of moves that gained them criticism from fans, Nintendo managed to pull together enough supply to curb the often ridiculously inflated eBay demand before it was too late."
