And what could be what happened to the Xbox One recently?

Risky prenatal surgery to remove a defect.

Hormone therapy.

The Wii was a massive mistake and I'll tell you why. It created a vacuum. Iwata traded in short term gain for long term viability. The Wii made them alot of money but at a huge cost, a cost we're seeing them pay for now.

Try it on Shahid Ahmad's twitter. You'll get the real answer in no time (But it'll take multiple tweets)

I don't understand why people think Wii was a mistake. It revolutionized the way people played games by being the first gaming system to use motion control as it's primary set-up. Just because the Move, floundered on the PS3 doesn't mean motion control is not a good fit for gaming.

Wii sales have meant nothing to Wii owners, game support has been pulled these wasn't really anything of note in all of 2012+

Wii owners now have to upgrade to wiiu only to play games that are made for ps360, so one can gloat about sales but them sales didn't give any return to Wii purchasers

to put it bluntly, Wii purchasers have nothing left to play unlike the other consoles where new titles are common place

I'm glad the whole soccer mom, casual crowd is gone to be honest. Good riddance. I think Just Dance is going to go the way of the dinosaur this year like Guitar Hero and Wii Fit will dissapoint sales wise. 

 As a Nintendo fan, we never got anything really out of this whole "we're making casual games now" bargain. All it did was chew up Nintendo's resources, the larger userbase didn't bring Nintendo any respect from third parties. We just got a bunch of crap shovelware and franchise spin-offs no one asked for.

I'm glad that Sing Party game for Wii U bombed bigger than the Hidenberg.

Nintendo started to lose support and that eventually led to its reduction in sales for each consecutive console generation. Plus, more competition came out and took in many people. The N64 had its hardware issues, so did the GCN. Now Nintendo has seemingly fixed any form of hardware issues that 3rd parties disliked (cartridges, mini-dvd, etc) and the problem now is the horsepower, though honestly it's not as big of a problem as the issues that plagued the N64 and GCN. At least, that's the only reason why I see the decline of hardware sales with each passing generation and why people have deemed Nintendo as "doomed status".

The market had grown and Nintendo was probably not dumb enough to make the same mistakes with the GameCube again, that a "GameCube 2" probably would've sold 30-40 million units if handled correctly, mostly on the back of Sony's $600 blunder and people having to go elsewhere for a while, enough to make a nice sized profit and continue making the franchises Nintendo fans actually care about.

And Nintendo became allergic to pushing games like Xenoblade because they were out chasing the casual dragon, I'm glad it's done with to be honest.

Casuals want $1 games on smartphones now? Good for them. Don't let the door hit yer ass on the way out I say. They won't be missed, nor will Zumba Fitness 234939 or Puppiez U or Hillbilly Carnival Games.
