For me NX will end faillure unless : they be home & portable in same time.
I think nintendo should stay losing 4 more years, and launch new home consol in same time as next sony & microsoft and have around same power so they can get tird party again and work from this !
IF they launch NX in 1 years or 2, will be so late, ps4 Xboxone will have so massive lead... and nintendo would have to launch again a new console earlier... and fan wont go with them if they support their console only 3-4 years.
