Lol are you two joking? PS4 sold about 14 million in 2014. You think they will sell only 11-12 million by December? 

Definitive possible.

PS4 have sold +3,000,000 in December 2014, so, 11,000,000 in the rest of year.

Considering that actually the PS4 sales is equal to last year, sure possible that this year will sell as in 2014.

(And nope, that is not my prediction, but is for sure possible)

September, they gonna release it in china until then. There it could sell at least as much as the xbox probably 500k, japanese sales are also increasing with every day.

Wow you're right, I thought in december it only sold 1-2 mil. However I think it's low. The PS4 will probably 2 mil over YOY especially with Uncharted and Japan.

Sure, even 3,000,000..... 16,000,000/17,000,000 is my bet.

According to VGChartz, from last years March 1st it took until somewhere between December 6-13 to sell another 10 million units. I'm certain this includes ever so slight under tracking. This year so far it appears that the PS4 is trending around the same level but we can also assume the China launch will provide at least a modest increase to baseline (maybe 10k each week?) along with a greater number of exclusives being released throughout the year and a projected pricecut coming before then.

With Uncharted 4 releasing this year as well to inevitable critical acclaim, I'm gonna say that to reach 30 million sold through, PS4 will do so halfway through October.  It really depends on timing of Price cut and Uncharted release however.

will the people who said 2016 please stand up

september

Yeah I take this post seriously, ps4 sales would have to tank for it to take that long.

Why post if you are just going to try to downplay something or at least not even use logic? PS4 would have to tank for it to take until dec, it did 1.7 mill 2 slowest months of the year, and it's still 399...............

December, that's always the one month where sales will always surge for most consoles.
