The two screens on Nintendo's just-announced 2DS are actually one large touchscreen, superficially separated by the system's casing.
This is according to a report on USgamer. Jeremy Parish, the article's author, says
the news was confirmed by multiple Nintendo reps.
The move is reportedly a cost-cutting measure. The casing separates the two sections of the screen, meaning that in hardware terms the upper half is actually touch sensitive. This is not being opened up to developers, however, and a piece of clear plastic sits above the top portion of the screen.
