Yikes. I'd rather Nintendo push NX into 2017 than release a consecutive inept mess of a console, but I doubt Wii U can limp through another holiday season. The focus should be on making sure NX is the best platform it can be, and the cost may be that Nintendo has little to nothing for six to eight months. One would hope Nintendo could get its act together and launch a competent console without its current console dragging itself to the finish line, but here we are. I'm on #TeamMakeItRight. Don't rush new hardware because you think you have to. Make it right so it has a chance to be successful. And hey, a 2017 launch increases the chances of Nintendo going with Polaris which might be worth the wait if its more than just AMD PR hype.
NX skipping E3 is disconcerting though Nintendo will have to unveil the thing at some point in 2016 if it's launching in less than a year. I'm not worried about that so much as Wii U's release schedule being a barren wasteland after Paper Mario: **** RPGs LOL. I suppose there will be some unannounced Wii U and 3DS games at E3, but I'm skeptical of any of them being enough to hold people over through a holiday season and a transition to NX.
I wonder if rumblings of Sony's PS4k/Neo forced Nintendo to reevaluate a 2016 launch, not out of fear but as a golden opportunity to strike during a potential moment of weakness. If Nintendo uses those extra months to load up on decent launch window titles and create a stable operating system and online infrastructure, it could be worth it.
