Yes. I have read about it on Nintendo's website, but you can find out more on March 27.
Yes, the Nintendo 3DS (as well as the 3DS XL and 2dS) has its own 3DS games that will not work for the Nintendo DS, Nintendo DS Lite, Nintendo DSi, and Nintendo DSi XL.
Yes, dsi games works on the 3DS also DS games work on the 3DS.
The Nintendo 3DS will be able to play Nintendo DS and DSi games but games published for the Nintendo 3DS will not be compatible with those systems.
3DS games can only be played on the Nintendo 3DS(XL) and 2DS. Therefore, Nintendo DS and DSi cannot play 3DS games
yes
It will fit, but it will not work on the Nintendo 3DS
No, 3DS games cannot be played on the Nintendo DS or DSi
Yes, the Nintendo 3DS has its own selection of 3DS games that cannot be played on the DS or DSi
No 3DS games and the system are seperate and cannot be used on another system.
If they were specially designed for the 3DS, no. There is a small tab jutting out of the side of 3DS games making them unplayable on a DSi. Even if you could fit the cards into a DSi, they would not work because they use 3D technology the DSi cannot utilize. DSi games will be playable on the 3DS though.
The 3ds supports all DS, DSI, and 3DS games. Like the DSI, it no longer supports game-paks for the Game Boy Advance.
The TTDS can't work on the 3DS console. But there is a new TT 3DS card, which can run DSi games perfectly on Nintendo 3DS console.
