They should, but I doubt that they will. First of all the 3DS will probably be more expensive to produce at launch, then the DS, if all the features are true ( 3D screen, rumble, tilt sensitive etc.). With the home console it depends a lot IMO on what the competition will price their system. I doubt that either MS or Sony will go above 400$ next gen. If the competition starts as low as 300$ they need the 250$, if not they could beef up the price to 300$. They are far more popular now then they where in 06, so they could afford it. Still it could hurt their marketshare in the longrun IMO.
