Oct. 30 (Bloomberg) -- Nintendo Co. fell the most in almost three months in Osaka trading after the video-game maker lowered its annual profit and revenue forecasts because of slumping sales of the flagship Wii consoles.

Nintendo fell 4.5 percent to 22,970 yen as of the 11 a.m. trading break on the Osaka Securities Exchange, the biggest drop since July 31. Japan’s benchmark Nikkei 225 Stock Average rose 1.3 percent, its first increase in four days.

Net income will fall to 230 billion yen ($2.5 billion) in the year to March 2010, Kyoto-based Nintendo said in a statement yesterday. The projected profit, the first annual drop in six years, missed the 270 billion yen median of 23 analyst estimates compiled by Bloomberg.

The company, which cut Wii prices 20 percent a month ago, yesterday forecast the motion-sensing machine’s first annual drop in shipments, citing a lack of strong software titles. The Wii ended its three-year reign as the best-selling console in the U.S. and Japan during September after Sony Corp. lowered the price of the PlayStation 3 by 25 percent, according to market research firm estimates.
