We can comprehend what's just around the corner (and what's already happening.) And it doesn't look good for Nintendo.
Nintendo is afraid of risk and change. The real danger is, is that when they *do* finally wake up and take action, it might very well be in the wrong direction (as we're seeing now with the 3DS.)
There is still time for them to turn around. After the Gamecube people thought similar things and this isn't nearly as bad as during the Gamecube generation (and look at Apple, they turned it around in a much worse situation).
Making iOS ports would kill Nintendo. The company may continue to exist but it wouldn't be the same company anymore. Hopefully they realize that pulse monitors for the Wii and tacking 3D on to the DS isn't the right direction and come up with something new (they need another Gameboy to DS evolution).
