"Optionality" is the key here people. The Nvidia Shield is streaming 4k 60fps Gaming from PC's on 3GB of ram and a chipset less advanced than a PS4. There are 4K phones that...ok, 4K phones are complete overkill but the point remains. The Roku streams Netflix 4K and cost $129.00. You don't have to be able to run native 4K gaming but push the tech as far as it can go, it's not expensive. Make the NX look as if it has plans to be around more than 24months. The point is while yes, 4K is not at the moment viable for gaming, it's time for Nintendo to stop thinking 6months ahead and think 6years a head. The Wii U has a phenomenal library of games on tech that clearly was only 6 months a head of the curve, if that. People will pay through the nose if they think they are getting their money's worth. This is the same company that put "Glasses free 3D" in a handheld, I expect them to step up to the plate and show me some ill **** this go round.
HDMI 2.0
USB 3.0
8GB RAM
That's all you need and that better be the bare minimum the NX has under the hood(4k or Not) or it'll be the same story.
