Because it will force Nintendo to TRY HARDER.
Fuck that noise.
As a current owner who is enjoying the platform and is excited for its future software lineup, the last thing I want is them killing it.
Try harder? Well, they can do that with the mess they have at the moment. In the same fashion they did with the 3DS; by building a respectable library and giving the system a proper push.
I sincerely doubt that even IF they turn things around to say, N64 numbers at best, they would repeat the strategy they have with this platform, again.
All anyone who's genuinely interested in their work wants at the moment more than anything, is great software and support to see this thing through a normal life cycle. They can go back to the drawing board then.
As it stands in regards to sales at the moment, yeah, this system is dead as fucking dead. Fingers crossed that the software dropped by the end of the year means the console is deserving of a new lease on life.
