One post from NeoGaf with I completly agree.
"My thinking is that they likely want to deliver on both sides of the spectrum. I believe they are aware that, to make this work, they need to deliver a great handheld experience, but also an adequate console experience. Otherwise, theres no point in going in this direction. I don't believe Nintendo simply threw an HDMI port on a decently powered handheld and called it a day, I'm sure they have thought of some smart ways to make the experience enjoyable on both ends. I totally see them trying to reach as close to console power in dock mode as possible to really nail the hybrid aspect. X2 makes the most sense, and Nvidia working with Nintendo makes me just a bit more confident. If they do go with Pascal, and reach somewhere near Xbox One in dock mode, and have a superior CPU, that should allow them to nab some big 3rd party titles and tout the fact that you can bring it anywhere with you."
Also lets not forget those very intresting Nintendo patetents with supliment base unit.
