1. Most people who will buy an NX will never own a Wii U, so the "consumer trust" argument flies out the window. If it didn't effect the Xbox, GBA, etc, it definitely won't effect the worse selling Wii U's successor.
2. They most definitely are not. E3 made that explicitly clear. That argument is out the window too.
3. Doesn't matter. New era. Also, that's not a benefit.
4. Also not a benefit. Just another reason to ditch the Wii U last year.
5. There will be 2017 games. NX games. Hence 2016's vacancy of any relevant games not already announced since January of 2013.
NX. 2016. It's happening.
