With a surprise announcement, with just a brief PDF posted on the Japanese investor relationship Website, here is the Nintendo 3DS! (PDF link)
No pics for now, probably we should wait for June, it will be officially announced at the E3, but that brief document tells us that:
- It will be sold in march 2011 (in Japan)
- It will be retrocompatible with DS and DSi games
- It will have a camera (otherwise, how it could be DSi-compatible?
)
- It will have two 3D screens, with no need of special glasses!!
Yes, you got it right, autostereoscopic 3D screens!! 
It's the SHARP screens that I mentioned exactly one year ago (for a cool coincidence, it was my first post on Dandandin.net!) about the new WOOO mobile.
Last time that Nintendo tried to make a 3D portable gaming console, the 1995 Virtual Boy, it was an epic failure, but this time? In my opinion it would rock!
Details like price and if it has a more powerful CPU are not yet revealed...
