My Wii U lifetime prediction as for now, is +19,000,000... So i don't think will sell 20,000,000, but for me will close.
Any way, i expect a sales between 18,000,000 and 20,000,000, maybe better than 20,000,000, maybe worse than 18,000,000, depend.
But according to the comment of this site seem that there is no way for Wii U sell this numbers.
I see comment like "will be a miracle for Wii U break 20,000,000". I disagree. Will be lucky if will sell 20,000,000, but "a MIRACLE" seem seriusly too much, a miracle can be 25,000,000 / 30,000,000, but 20,000,000 is so hard?
Most people say "because Wii U is below GC..." Ok, but:
1) But Wii U can break 20,000,000 even withouth outsell GC!
GC sales are 21,740,000... with 20,000,000, Wii U will sell under GC.
2) GC was selling for 99$ in the same time... Wii U is still at 299$...
GC sales are dropped like a rock by 2004, because the price was already accessible by 2003, and the most people have bought a GC the first two year...
Wii U can still have many pricedrop in the next years, 299$ ------> 249$ ------> 199$ ------> 149$ ------> 99$ ecc, so, the sales is not gonna to dropped hardly like GC...
3) As i say, GC peak was in the second year.
Wii U can of course break the peak this year, in 2015... we will see...
Last year was Mario Kart, but after that, nothing. DK was nothing. Hyrule Warriors was nothing. Bayonetta was nothing. Smash Bros was nothing. yes, Smash Bros was nothing. The reason is easy: 3DS released (before Wii U), and no bundle. 3DS was a Smash limited bundle... Smash have help 3DS more than Wii U... So, is ridiculus say "i don't see a sistem seller like Mario Kart and Smash Bros " because Smash Bros was NOT a sistem seller! Damn, XenoBlade X in Japan is gonna to sell more Wii U than Smash Bros, even if Smash Bros is coming in December... A pricedrop can be easy much bigger than Smash.
4) Wii is released 5 year after GC released (4 in Europe)... if the new Nintendo home will released after 6 years Wii U launch, Wii U can have a intere year of advantage than GC, and this will of course make the difference. The "NX" actually is nothing... can be all, most likely will be the new Portable. i don't see "4DS" released in 2016 honestly... 3DS is still selling massive, and is massive up compared to last year Globally, in US, in Europe, and only 10% down in JP. So, i think is more likely a new portable in 2017, and the new home in 2018...
Now, a possible scenario for the Wii U sales (not my prediction):
2015: 4,000,000
2016: 3,500,000
2017: 2,500,000
2018: 1,200,000
2019: 600,000
2020: 200,000
TOT: 21,000,000
That is not my prediction, but of course is a possible scenario about Wii U sales...
Any way, do you think that Wii U have absolutely 0 chance for sell 20,000,000? vote in the poll.
Also please, make a sales Year on year for the Wii U sales, will be even more easy for know your opinion...
