So Reggie just went directly against what Kimishima and Iwata have been saying about the relatioship between the WiiU and NX.
The NX was supposed to be sold alongside both the 3ds and WiiU and not be a simple replacement for either one system. By saying that thei're transitioning to NX we can at least confirm that it is indeed a replacement for wiiU. If it will also replace 3ds we will see.
