I don't care much for the NX rumours at this stage, so i guess I don't really care. Off the bat, it sounds more like the classic expectations turn into rumours that anything else.
Even if it is truth, I bet that it won't be by much. They did the same rumour about the Wii U.
With this said, I gotta agree with the sentiment that they need to develop new IPs, make things easier for third parties to develop and convert, as well as going back to focuss in how a game bring something new instead of how to make a controller that brings something different.... and drop the "Wii".
