Wii U has sold 0.7m in almost half a year. It's only going to be worse after NX is announced. I'll stand by that 13m :')

Well once NX launches it will be a 9th gen console (well that's how some count gens), so Wii U sales will dry up and NX will have 100% of the 9th gen home console market (again using the gen counting that I see others use), leaving the battle of the 8th gen only between X1 and PS4, sooooooooo, PS4's percentage is just gonna keep rising.

That's mean nothing, and still even if NX will release in the holidays 2015, still WIU will sell more than 13m...

Just for know, what do you think will sell LT Vita? Hope you predict less than 13,000,000...

Not sure why people think this gen will be as long as last one, when Sony/MS have said that it won't be.
That being for obvious reasons of them having sold consoles for profit from beginning,
and both architectures barely being differentiated from PC x86 architecture = less power/optimization potential.
(e.g. in contrast to PS3 whose potential really was impressive when released)

Regarding sales projections, the starting point we have is PS4 is to-date/currently outselling XBone by ~2:1.
WiiU seems to be petering out, and it's % seems highly likely to seriously decline, which it has since S/M launched.
XBone isn't going to do better than 1:2 vs PS4, and honestly I think PS4 will do better than 2:1
just because of the dynamics of growing install base, more games going to PS4 (for install base),
people flocking to the most successful platform, etc... Not to mention if any party is going to delay their next gen
it will be the most successful platform, namely Sony, so they MIGHT have an extra year of sales if they so choose.
(not to mention their ACE/GPU Compute advantage has alot more optimization potential than XBone)

To really expand the lead vs XBone, PS4 will need to take over MS' "turf", and I would say that means
they need to claim some solid AAA FPS... Exclusive marketing with 3rd party e.g. COD is a start on that,
and continuing to demonstrate PS4 is the best platform for x-platform games will be part of that.
(3rd parties being able to fully leverage PS4's compute advantage will be crucial, which IMHO is now happening, e.g. Project Cars)
Outside of FPS, PS4 doesn't have any problem, I would say they have stronger IP outside of FPS.

Another "breakaway" factor not mentioned here is Project Morpheus, which opens up a new vista of gaming.

There also is another dynamic at play, namely that of "second console" phenomena,
and if PS4 is consistently demonstrating superior x-platforms, AND "must have" exclusives in all genres,
not to mention Project Morpheus, then many XBone gamers WILL ALSO end up getting a PS4, both for exclusives and x-platforms,
while relatively few PS4 gamers will do the opposite... That is what can help push PS4 to 70% or even above.

(personally I wouldn't bet on above 70%, though ~65% seems quite do-able)

That also brings up a related topic, share of games sold... PS4 x-platform superiority and "second console" phenomena also favors Sony here IMHO, and Sony's marketshare in this metric may likely surpass their console %.

nope,if NX launched Holiday 2015

then you cud as good as hope WiiU to even stop at 11m

...Again what?

Any way, ok, wanna bet? I predict WIU at more than 13,000,000 lifetime. If will sell more i won, if will sell i lose.

Accept?

These 100M max predictions for PS4 are hilarious. PS4 is going to be the highest selling PlayStation of all time. 180M is the minimum, and this gen is going to last tell at least 2020 before we see new hardware from MS and Sony. Once the dies for the APU's shrink, we will see a slim PS4 at $299. PlayStation Vue will be out across the US, and Project Morpheus will be making the Wii look like niche fad. PS4 is going to be the first console to sell 30M units in a single year, and it is going to happen at least twice.

PS4 - 180M 66%
XBO - 80M 29%
WiiU - 14M 5%

ROFT.

do you even know, how math works?

xbox is at 12m units already
wii u is at 9m units

even if they don't sell any more consoles in the next 10 year, the ps4 need to sell 210 million units, to achive 90% marketshare

80% or more marketshare is not possible
only if sony pay a 100 bucks to buy an ps4


ps4 could achive 60-70% max

11m wiiU
29m xb1
134m ps4
would be 70% marketshare

any for any more wiiU or xb1 sold, sony need to sell 3.4 ps4 to maintain the 70% marketshare

Again, Sony (for sure) and MS (I'm pretty sure) have themselves both stated they don't expect this gen to be as long.

Why should it be?  It was profitable from Day 1 (on per additional unit basis), and the next gen will easily be backwards compatable,

meaning there is no disruption in continuity, in fact devs can release "cross gen" games which are really last gen games but with a setting

that automatically "bumps up the graphics settings" when playing on the new gen console.
