Nintendo's failure to anticipate the demand for the Wii and its inability to ramp-up production are seriously restraining its growth. Furthermore, Wii console shortages have encouraged Microsoft and Sony to slash Xbox and PS3 prices and capture many would be Wii buyers.
The Wii shortage is best evidenced by the continuous sales of vast numbers of Wii consoles on eBay at substantial premiums above MSRP. Meg Whitman, the CEO of eBay, needs to send a special Christmas present to Satoru Iwata, Nintendo's CEO, thanking him for all the business the Wii shortage has brought to eBay. She might even suggest that Iwata invest some of Nintendo's abundant cash, which totals about $8 billion, in eBay stock while the Wii console shortage persists.
It is understandable when a manufacturer misses one Holiday selling season because of insufficient product. It is unacceptable to miss two in a row.
