The premise is fine, but in terms of power level and price - its positioned horribly between PS3 and 360 - which are still selling well - and next gen machines, which appear to be viewed as a better investment. They can't fix the power, they have to fix the marketing, the price and what offerings are available. And thanks to fucking it up so badly to begin with, they can't rely on any third parties to help them do that unless they're willing to sign some big cheques.
"OH BOY! I CAN'T WAIT TO PLAY MARIO #20599023405834900598308 ON THE WII U!"

(Radiohead: BUT THIRD PARTIES!)
Okay, let's play that game:
"OH BOY! I CAN'T WAIT TO PLAY BATTLEFIELD 5 ON WII U WITH 16-32 PLAYERS WHEN BATTLEFIELD 5 ON X-BOX U AND PS4 DOES 64!"

"Fixing offerings" isn't going to help. Mario didn't help. Pumping out more of that/Nintendo first party isn't going to help. And even if
they did bring third parties back (

) Nintendo fans like you won't buy that and anyone with a lick of common sense won't buy the Wii U version when the "next-gen" offering has more players, better textures, etc. going for it.
"Better marketing" is going to amount to the above sarcasm "OH BOYS" because again: Mario didn't help. Nintendo fans were touting that as the second coming of Jesus and the press liked it, but
no one wanted to get a dead system for it.Nintendo needs to admit they fucked up. They need to sack Iwata TODAY and get the R&D team to go to Sony/Microsoft's stores, buy their consoles and play those for a year while coasting on the 3DS's mild "success" and then rebuild their entire console infrastructure to meet the Sony/MS demands. Because, clearly, they didn't do that in the run up to launch (Eurogamer story here).
It's dead, move on. The 3DS is awesome so play that.
If Nintendo thought along those lines themselves, the 3DS would still suck.
The Wii U is a better, more enjoyable machine in every way aside from the games library edit: and cost of entry of course. I don't really care if it does sub Gamecube numbers as long as good games come out for it, but it would be nice if they were able to salvage something more.
3DS at least has "Nintendo dominance of the market" as a shield to hide behind while it floundered, plus it's "gimmick" could be ignored by the masses that didn't like it (see: me) while still having a functional "DS" successor otherwise--I'd buy a 2DS, meanwhile. Still haven't done that... need to do that... but nope. Not yet.-- Plus it doesn't
need the online functions a "next-gen" console needs. It's nice, but it's a portable and that means it's going to go into areas where wifi may not be (on a camping trip, for instance) for short-bursts of playing before doing something else in those areas. So the 3DS also has the "not the same market" excuse that the Wii U doesn't in comparison to the PS360/PS4/Xbox.
Wii U doesn't have that excuse or shield. The Wii was a fluke after two luke-warm console generations. The 64 wasn't terrible, the Gamecube was kinda terrible but still sucessful. But the Wii U is tracking
far behind that one[/i] to be chugging along on the train-tracks of success. It's derailed. Time to accept that, clean house, and rebuild the company if they want success in the console market.
