Keys Factory employee hints at possible Nintendo 3DS release date for Japan: November 20th, 2010. For those unfamiliar with the company, Keys Factory produces many of the DS/Wii/PSP accessories we’ve featured here, and it recently worked with Nintendo to release that “Human Tetris”-style game Surinuke Anatoosu on WiiWare.

This tweet, now deleted for obvious reasons, reads:

“On November 20th, the 11 goods I designed for use with the 3DS will go on sale simultaneously. Those of you buying the 3DS, please buy them while you’re at it! This will be officially announced on the homepage eventually, lol. Best regards.”

Please note that even if the release of Keys Factory’s 3DS products coincide with the system’s launch, this doesn’t guarantee that the 3DS launch will come to North America by the end of the year — March 2011 seems more likely, in my opinion. Anyway, we’ll here official details soon, as Nintendo reportedly plans to formally reveal pricing and a shipping date for the new portable on September 26th.

And if November 20th seems too close to the holidays to be believable launch date, please note the previous release dates for some recent Nintendo systems in Japan:

• DS Phat: December 2 (Nov. 21 in U.S.)
• DSi: November 1 (April 5 in U.S.)
• Wii: December 2 (Nov. 19 in U.S.)

Buy: Nintendo DSi XL (Blue, Burgundy, & Bronze), Standard Nintendo DSi (White, Pink, Black, & Blue)
