No one cares about 3D and the most difficult thing with the 3DS software will be games where the second screen is used, not only for issues with the touch screen but to display information. It would require Nintendo and other developers to come up with a work around and it is questionable if they will see that worth the effort.
Which is probably why they are still trying to support the 3DS into next year.
