And be replaced by whom?
By people not stupid enough to release glorified iPad games for 30-40 dollars. People not stupid enough to see overpriced software collecting dust on shelves and do nothing to change the pricing scheme. People like that. And perhaps people that see the value in cultivating a strong western third party presence so that their consoles/handhelds might not flounder in the West as they are.
3D Mario, Zelda & Mario Kart. 3 System sellers right there (How many systems is debatable of course).
All those hit the 3DS and yet it's still pretty much flopping in the West.
