I think the 'Wii U is d00med' nonsense will stop after the Christmas shopping season has come and gone.
It's going to have an installed userbase over 8m before the end of the year. And that Motley Fool article didn't mention that the bad start that the Wii U has had has left it with an installed userbase just 1.5m short of the 360 during its 1 year head start. Hardly a disaster.
8 million before the end of the year? It would need an average of over 510.000 per week, starting NOW (!) in order to do that. Note that the best week it ever had was about 560.000 and it was never supply constrained, you expect it to nudge close to this number on average for the whole rest of Nov/Dec. There is simply nothing at all pointing towards such a thing being even remotely possible outside a fever dream, that would beat the One, PS4, PS3 and 360 and be pretty close to the 3DS in sales and likely require one or more million selling week(s). No way.
I just have to ask; are you serious? Do you actually believe this will happen?
In my opinion, it's gonna have to fight to get over 6 million by year's end.
Also, for the record, the 360 was at nearly 6 million after one full year on the market and over 8.1 million after its second holiday season, the Wii U is tracking about 2 million behind at this point. The PS3 was over 6 million after one full year and at around 9.5 million after the second holiday season, tracking way above. Both the 360 and the PS3 had fairly slow starts and the PS3 had a ludicrous price tag and a staggered launch and both HD consoles had shit software for quite some time do drive the sales.
In all honesty, you and a lot other users in here need to get your head out of the sky and look at the cold, hard facts at hand.
I think at this point, this whole argument of the OP boils down to semantics; what is your definition of doomed?
Edit; I need to correct my numbers, the Wii U actually need in excess of 580k weekly average from now to cross 8 million by year's end, that's 15-20k above its best week ever, on average, for the rest of the year. Please let that simmer for a while.
End of 2016 hardware sales:
Wii U: 15 million. PS4: 54 million. One: 30 million. 3DS: 64.8 million. PSVita: 15.2 million.
