To be fair Nintendo thought of all this in advance, that's why we can switch the 3D effects off, right? I'm buying my 3DS when it's available because with the effects or not, it's a great looking system with a decent game library on the way. If I find the 3D harmful, which I seriously doubt, then I'll just switch it off. Either that or I'll just play DOA Dimensions with the effects on. That way I'll start to subconsciously associate 3D effects with bouncy bewbs, and I won't be able to complain about them
