Lol ? So for you, Wii U can live and get games without Nintendo ?

The Wii U is dead. It's been dead for awhile now. There's no reason to mourn it's death, Nintendo needs to move on.

Nothing at this point could turn the wiiU into even a moderate success.

No it isn't.

It's speculated as not happening because Tanabe said that, if he started working on it now, it'd be on the NX because it would take about 3 years to make. Like what so many Americans do when reading their Second Amendment, the context has been stripped away in most reporting - they report him as saying "So it would likely now be on Nintendo's NX console". But the sentence before it was "If we started for Wii U now, it would likely take three years or so." What he didn't say was that it hadn't been started, yet. And this was from Eurogamer, and even they recognised that it wasn't a confirmation of anything, because later in the article they say "This all points to Wii U not seeing a new Metroid Prime (or just Metroid), which is a shame..." - "points to" is another way of saying "implies". And implication is not the same as confirmation.

It's not a "confirmation" unless they say "Metroid Prime 4 is not being released on Wii U" or some variant thereof. And when he words another answer as "I'm not thinking about anything like that [partnering with another studio] right now. We have nothing to announce on working with any specific team." - the part that should stand out is "nothing to announce". If Tanabe was confirming MP4 wasn't in development for Wii U, he'd have said something like "We aren't yet at the stage of considering a studio to partner with", not "we have nothing to announce".

If Nintendo released Zelda this month and another franchise title in August 2015 (Kid Icarus, F-Zero, Metroid, Animal Crossing) then I think the Wii U would have experienced a revival for the holidays.

It doesn't need to be saved. Nintendo actually makes profit on each unit sold. Maybe it doesn't print money like DS/3DS or Wii, but still ... no loss. Of course they could drop the price to some ridiculous level, invest shed loads of money in advertisement, pay 3rd party devs to release some games (as their support is practically non existent), put all their resource in developing new games etc. But considering current Wii U situation this would be extremely risky and might not pay off. From business point of view, it would make much more sense to do the same thing but with the new system. At the moment every new Wii U game is selling very well and they make quite a lot of money on amiibos so I guess for them it's good enough and now they're simply moving on. 

Didn't he like say that he couldn't collect a team to do the game though?

Honestly nothing. Only a new IP would save it and it's a bit too late for that

Its dead because of nintendo choices, the GC was in the exact same situation but they supported it better and it became one of the best console ever, a shame they choose to move on

I think you're referring to this: "It is a great idea, I agree. Truth be told, making HD games takes a lot of time and resources," Tanabe concluded when asked why Nintendo had not made a Metroid Prime for Wii U. "I haven't been able to collect a team or the resources to do it."

The part where it specifies what he was asked changes the way you read it. If you assume they asked "Why aren't you working on a Metroid Prime for Wii U?", then yes, he said he couldn't collect a team to do it. But if we assume the question was more along the lines of "Why isn't there a Metroid Prime for Wii U, yet?", then his answer is more along the lines of "the people we'd be working with were busy, we'd have had to form the team by 2012 and they weren't available at the time".

Anyway, the point I'm making isn't "Metroid Prime 4 IS coming", but "it's not confirmed, just likely, to not be coming".
