Developers will not be forced to use the 3D effect on the 3DS

This information comes from the latest Iwata Asks…

“Right. It’s compatible with software for previous Nintendo DS systems, which will be viewed in the 2D mode. New game cards, however, will be specific to Nintendo 3DS, but whether they will be in 3D or not is basically up to the maker, just like how much to use the touchscreen was up to developers for Nintendo DS.” – Shigeru Miyamoto

So far, we haven’t seen any title that doesn’t use 3D. It goes without saying that a very small percentage of games developed for the 3DS will only support the 2D mode. Still, it’s nice to have the option available.
