Re: Launch of New Portable Game Machine
Nintendo Co., Ltd. (Minami-ward of Kyoto-city, President Satoru Iwata) will launch "Nintendo 3DS"(temp) during the fiscal year ending March 2011, on which games can be enjoyed with 3D effects without the need for any special glasses.
"Nintendo 3DS"(temp) is going to be the new portable game machine to succeed "Nintendo DS series", whose cumulative consolidated sales from Nintendo amounted to 125 million units as of the end of December 2009, and will include backward compatibility so that the software for Nintendo DS series, including the ones for Nintendo DSi, can also be enjoyed.
We are planning to announce additional details at E3 show, which is scheduled to be held from June 15, 2010 at Los Angeles in the U.S."
So this means a...
- New Handheld
- 3D without needing glasses
- Backwards Compatible with DS and DSi
How the shit they're gonna pull of 3D without glasses whilst still making it affordable... I do not know but if its got some graphical compatibility updates (other than the 3D thing) then they've got me sold.
