We still got another year/year and a half right? They should work with someone to be the very first Cloud based system. It would be something brand new for Nintendo owners due to the need of the strongest online tech available, as well as a REALLY sizable hard drive if all games are digital. It would reduce costs of video game production drastically no more disks/cartridges/flash cards/ect, no more packaging costs, no shipping costs, ect. After the initial release (which would have the once packaged game pre-downloaded) all other games can be preloaded to a certain percent to be fully downloaded the day of release (like Splatoon). Once a game is downloaded, it can be played whether you are connected to the internet or not (like Splatoon). The only hickup would be sharing with friends... Not sure how you would do that, and not just allow one person to buy a game and making multiple copies to give (or sell) to other people.
Beyond that, emulate all the other systems (hell, everything but the Wii U is already emulated through the Wii U VC anyways. This would take almost 0 effort).
Make Miiverse 2.0 where you can share videos (full playthroughs even), and add videos like reviews, fan content, ect (I already had another thread discussing this) with a rating system for best videos to appear at the top.
This would also make it practically effortless for third parties to release games on the system (taking out all the questions of things like how many copies to produce in disk form, and where to send these copies). Make there system X86 in architecture and have it to where these teams have to do little more than push a few buttons to get these games on the Nintendo network.
And hell, you can call the the Neo (Nintendo Entertainment Online)
