The comments at the end of that article are ... feverish.
The one that starts with "i didn't even read the whole thing, what a load of bollocks" was the best. I feel like I'm listening to audiophiles explaining why 16-guage lamp cord is worth ten bucks per foot. The next console is a USB stick that plugs into a smart TV. The next handheld is an app for various phones. The first old-school game developer that gets this will have another decade of cash. Nintendo started out as a playing card company. This may explain why they still aren't seeing that that they don't need to invest in hardware. They could build a modular API, then introduce games from their famous stable that use the API on various platforms. On one hand, the hardware lock-in from building your own console solves a lot of problems for developers: they know exactly how the software will work each time. However most of the people that would buy a portable game player already have a smart phone and no other front pocket space.
