It was pretty much implied when "backward compatibility" was listed as a feature of Nintendo's new 3DS handheld back in March. But it's good to hear that 3D gameplay can be easily switched off, direct from Nintendo president Satoru Iwata, when headaches or nausea set in during marathon sessions. This should also ease concerns from parents over any adverse effects that long term exposure to parallax barrier gameplay could have on their children's developing eyes. Besides, a 2D mode is desirable in that we expect it to offer a brighter image (especially when viewing off-center), better text reading experience, and a wider angle of view for sharing the display.

Now, we know what you're wondering: what about that new 3.4-inch glasses-less 3D touchscreen display from Sharp, is it 2D switchable? Yup, lending more credibility that we'll see it on the 3DS when the handheld gaming console is fully revealed at E3 next month.
