The NX, which as Adrock has pointed out has been more or less "outed" as a console, should be out in 2016 but probably won't be out until 2017. It should in the sense that the plan to replace the Wii U should have started pretty damn early and I figure Nintendo took a while to admit the problem. They're slow so I expect 2017 and, yes, I expect jack **** for the Wii U in that time and then Nintendo will wonder why no one gives a **** about their new console when they've disappeared for two years.
Perm suggested that consoles are peaking. That's what we all hoped this time, that the need for the PS4 and XB1 wasn't there and those consoles would flop. Well that didn't. It all seemed at the time like we could make due with that level of graphics but things changed and we saw we could do better. If Nintendo is relying on graphics to peak that's a big risk.
No Metroid and likely no Zelda. Anyone else see the Saturn parallel when Sega didn't even get a real Sonic game out for it?
