Why the next Nintendo console could be - "Wii 3D"

[NJ5]

Very few people have 3D-capable TVs, that is the problem.

Well a current TV could do 3D, but at 30 Hz per eye which is way too low. It would mean flickering and lots of headaches.

So no, I don't think 3D will be mainstream soon enough for this prediction to come true.
