Uh, the corporate strategy for high market valuation is to use the captial to make a strategic acquisition of a key partner or rival. That's totally common place in America 'cept in Japan they have some honor bound cultural bias against mergers and acquistions.
Some market caps for comparrison:
Sega-Sammy - $4.8 billion
Capcom - $1.1 billion
Namco Bandai - $4.1 billion
Konami - $2.9 billion
Square Enix - $3.7 billion
Yeah, it'll never happen but one would hope that the strategic planners inside Nintendo are exploring the options.
Nintendo was worth a measly $18 billion just a year ago, btw.
Stock price falls and so does the capital.
