In case you didn't know, at the same time Sony announced the 18.5 million PS4s sold through figure, they also said 81.8 million software units had been sold.

The date varies a bit for each region, but it's somewhere around 2nd-4th of january. Now, VGC has PS4 total SW at 85.4 million at the same point in time. That makes it a 3.6 million overtrack. But that does not take in account that the 81.8 million figure almost deffinitely includes digital, which will at the least be 5 million IMO (and I'm being cheap now, it could possibly be as much as 10 million or even more). So PS4 total software is overtracked anywhere in the region of 3.6 (zero digital sales, lol) to ~15 million. The actual figure is probably somewhere in the middle, maybe ~10 million.

So when will VGC update numbers to reflect the announcement? ioi?

I can tell him which games are most likely overtracked then

The Evil Within

Call of Duty: Advanced Warfare

GTA V

Far Cry 4

Alien Isolation

Watch Dogs

Destiny

inFamous: Second Son

Middle Earth: Shadow of Mordor

I might've forgotten some, but most of those are pretty obviously overtracked.

Aren't nearly all adjustments on this site based on what is "probably over"?

imo the games that are probably overtracked aren'tt the big ones like FIFA and GTA,it's the "niche" ones that were selling "too good to be true" like alien isolation.

Yeah, Watch_Dogs, Destiny, COD AW, AC Unity, and GTA V and before all Drive Club are overtracked.

Driveclub by a lot...

But see, there's the thing, ioi never ever knows exactly what regions need to be adjusted. (unless he's off from NPD of course).

All he knows is that it's not Japan, and not US. but for software he wouldn't even know that, because many of these titles we don't get NPD leaks for. He can't just refuse to alter a definitely wrong number because he doesn't know exactly where it's wrong.

LOL I was thinking of making a thread like this but Teeqoz beat me to it.

I agree with Ryng_Tolu those overtracked software should come from those games especially Driveclub. Alien Isolation is overtracked as well like Otto stated(as well as other versions of the game).

Both xbox one and ps4 have many games overtracked. Gta 5 ps4 is not one of them though.

Um...yes it is.

I'm sorry but on ps4 it really has sold that Well. Hard to believe and all
