UPDATE

Of course I'm talking about CURRENT, HANDELD generation. The 3DS is hot-selling, but it's not the same strategic importance in terms of profitability, options and marketing.

Also cry and continue to be desillusionned (not in synch with reality), again there is NO DOUBT that the Wii U will either be somewhat saved by selling a side system but not enough to save Nintendo a living room console maker, OR it will even totally sink and not sell enough.

I'm saying as a BIGGER and probably older fan of Nintendo than most the unreasonned fanboy who will cry and deny this like Microsoft DRM supporters in a few month, but the Wii U WILL FAIL, because of it's own concept and hardware that can't be change.

Let's put things in perspective :

1.
The Xbox 360 was release in 2005.
The PS3 and Wii were released in 2006.
The Wii sold the most console for this generation (99.5M) but the PS3 has sold more than X360 altough it was release one year after.

2.
The PS3 is selling almost twice more than X360 which is great momentum for the current and also the next generation.
The Wii however is not and has not been selling well for two years now.

3. 
Hence the Wii U is really a failure sale/attraction wise. There's no getting around it : it's selling less than current consoles, it's selling less than the PSVita (and of course 3DS, but they're both handeld, just making a point for non hypocritical fanboys), it's selling less than the Wii and according to recent number, there's more PS4 and Xbox One pre-orders monthly than Wii U sales.

In fact the PS4 has 2 pre-orders for one Xbox One, and most relevant analyst predict 3 to 4 PS4 sold for 1 Xbox One (I agree with the 3:1 numbers for this year)

Conclusion :

This generation is not set up. In fact before comparing consoles I have to remind you : there's never been so much changes and threat to the consoles than now (PC, Moble, Homebrew, TVs...).

But the Wii U IS BY ALL MEAN A FAILURE. It WILL NEVER get better because, deal with it, the context has changed, it's not the Wii era 2006 but the next-gen era 2013.

The Battle will be between the PS4 and Xbox One. The DRM debacle gave the PS4 a big headstart but as usual the casual and couch potatoes will decide which one wins, nowing that in Asia the Xbox One won't even be available as well as in many other countries, that currently the PS3 outsold the Xbox 360 in Europe and Asia, and the X360 sold more in the US, but is now selling as much as PS3.

Don't count out the WiiU until Nintendo calls time on it.

That's not exactly an educated assumption. This holiday the Wii U will have the most impressive lineup, I think we should wait until after the games hit to call it a failure. Sure it's doing very poorly right now, but saying: "It WIll Never get better because deal with it this is not 2006" is pretty dumb. 

Also, you fail to mention the 3DS which is handily beating the shit out of the rest of the consoles. 

People are too quick to write systems off. This guy was probably calling the 3ds a total world ending disaster after its first six months on the market. You can only say for sure if the system is a failure after two or three years when plenty of software has been released. It really does get boring on here when people constantly say that something is doomed. its obvious the video game market is smaller. The vita will sell less than the psp, the 3ds will sell less than the ds, the wii u will sell less than the wii, and lets face it the same might apply to the ps4 and xbox one. Its a declining market but that does not make any system a failure, its just been a damn good generation for sales this time around.

When you say the Wii sold the most consoles ever, you mean for this generation right?

The 3DS is a handheld console so I think it should'nt be compared to Home Consoles. Compare it to the Vita and yes it is kicking its ass.

Im dealing with it. Thanks for the advice.

The Wii isnt even remotely the best selling console ever - . -

I think he got confused. The whole arguement sounds confused really.

poor wiiu , but it'll get better let's see how it does when them games start coming starting from pikmin in august if by december doesn't get momentum then maybe it's in more trouble , but don't underestimate smash and mario kart
