For me NX will end faillure unless : they be home & portable in same time.

I think nintendo should stay losing 4 more years, and launch new home consol in same time as next sony & microsoft and have around same power so they can get tird party again and work from this !

IF they launch NX in 1 years or 2, will be so late, ps4 Xboxone will have so massive lead... and nintendo would have to launch again a new console earlier... and fan wont go with them if they support their console only 3-4 years.

yeah its pretty straight forward in all actuality, no real rocket science needed. Cloudman basically summed it up

From last year sales of 3DS/Wii U hardware will be only worst, Nintendo in 4 years would be in very bad situation without new hardware. At end of next year 3DS will have around 6 years, Wii U around 4 years, if its a NX really hybrid of home and handheld console it would be perfect time to release it at end of next year, and device like that wouldnt compete directly with PS4/XboxOne, similar like Wii. After NX their next console can be around 2020/2021.

Why shouldn't there be hope? Fans of PS hoped PS4 would perform better than PS3, It's the best thing for fans if the thing they like is appreciated by others. Nintendo makes fantastic games (and this is coming from an old Sega fan who despised The big N back in the days) and deserve to sell a lot more. That 3rd parties only run where the money is is only a sad statement ago the industry, not Nintendo themselves.

Are those Vita games all retail?

Since when was the Wii a failure, underperformer or poorly exectuted? I think you misunderstand the quote or I wasn't clear enough. My point is that in follow up generations of success ones, console makers often become complacent or cocky. So following on from the Wii Success, Nintendo thought that they had a 100m casuals waiting at the ready to buy anything with the name "wii" in it, they've said this themselves. Equally sony thought the same when they introduced the $600 PS3 and built the system in an "ivory tower", not giving much of a damn about what devs wanted or making the platform easy to develop for.

I don't know of anyone who expected the Wii U to outperform the Wii

Many people resented the Wii for its emphasis on casual gamers but its first 3 years on the market were executed to perfection, from the conceptualisation of the console, to the marketing, pricing and software. There really wasn't much to improve on, mayb you're talking about its end of life support? 

This is completely true, Nintendo stated they were little intoxicated and to relax after Wii/DS success, they were assuming millions Wii owner will right away buy Wii U even without marketing, something similar like Sony done with PS3, only difference was that Nintendo made many very serius mistakes with Wii U so they don't really recovered sale of Wii U, only real PS3 problem was high price.

Nintendo with Wii U failed in every possible way (expect great games), its most biggest commercial failure for Nintendo (if we don't count Virtual Boy), and they will certainly work hard to correct those mistakes with they next console, thats why many people expect that NX will sell much better than Wii U, but certainly no one expect Wii sales.

Is this a pre-doom thread?

People are angry over imaginary things?

I made that clear I was talking about the end of its life. Nintendo knew the system lost those people for the last 2/3 years. And the 3DS also showed this as well. It was a gamble they shouldn't have aproached like that. Read some old threads. People where all hyped and happy about Nintendo going for core people. And won't do the same mistakes in several areas, etc. It's just the same hope for the best, that people give to Nintendo. And then where back to the things they chose to do. This time I'm just not gonna buy into their presentations or hype that people build up. I'll wait for sales numbers and reviews for at least a year.
