I would say Nintendo Direct
prease stai tuned

They used to have a magazine called Nintendo Power.
A thing called the Power Pad that you put on ground.
Who could forget the Power Glove? That futuristic controller glove was awesome looking.

How about
NES Power or Power NES

IMO they should definitely drop the Wii branding, if it is a combo of home system with a portable then Nintendo Fusion would be cool.

If it's going to be another console for home by itself then I think just calling it something like the Nintendo ES, ES for Entertainment System would be cool. Maybe even write it like this N-ES.

Anything too complicated doesn't work, Wii U wasn't distinct enough from Wii, so many gamers didn't even know there was a new Nintendo console. The naming of the console needs to be spot on by itself, to market itself with the name alone.

With each proceeding console Nintendo should keep the N-ES and like Sony have the numbering system, like
N-ES 2.

Wii Too

Actually expected the Wii U to get that name, as it sounds exactly like Wii 2

And if they want to drop the Wii brand: Nintendo Power

Nintendo Super WII

I think you're gonna have to clarify what you mean here, am I missing something?

Nintendo Nosotros...

Fusion would be the name of Nintendo's handheld/home console combo that some people, especially soundwave, are banking on. Considering the word Fusion means to put two things together I thought you would be alluding to the fact that that's what you want Nintendo to do next generation.

NEW Super Nintendo Entertainment System.

Oops lol. I completely forgot about that. I was going to say Galaxy, but that sounded too Sega for my liking so I went with Eclipse. Duhhhh. Heheheh.
