According to Eurogamer, the Nintendo Switch’s screen will be 720p, 6.2 inches, and will have multi-touch capabilities.
For comparison, the 3DS’ screen is 240p, and the Wii U gamepad screen is 480p. The Switch will be Nintendo’s first HD “handheld”. While it is a home console, it’s still a handheld as well.
The Wii U gamepad is 6.2 inches as well, the same size that the Nintendo Switch will be.
The Switch is also Nintendo’s first multi-touch device. The 3DS, Wii U, and DS were all single touch.
Unless another company makes a surprise announcement, the end of the 3DS’ support will also be the end of dual screen gaming for the first time since 2004.
