Doesn't matter to me what date it's from since it's not a milestone number anyway.   When the PS4 hits 15m sold-through I'm sure Sony will make an official announcement.

That's only where they cut off the video at the beginning, there was no sign that that's the final figure they'd reached by PSX. PS4 had shipped 13.5 million by the end of September, there's no way retailers would be ordering that many if they weren't going to sell that number at least by the end of October.

IMO VgChartz is under tracked, which makes sense because of a number of factors, like VG doesn't even have PS4 at 10M when Sony announced they'd sold well in excess of 10 million back in August. When Driveclub launched there were two other major releases, but the sales dropped compared to the previous week when Shadow of Mordor launched, SoM was a pretty big seller, was still on the markey, yet despite there being 4 new games on the market and a highly anticipated 1st party exclusive the numbers still dropped like a stone.

COD AW sold a million more on PS4 than XBox One, according to VGChartz, but the rise in hardware sales was nowhere near as big as Xbox One, which makes no sense.

17M seems like a minimum at this point, obviously sales hadn't reached some milestone that Sony felt they wanted to share, my guess is that they now want to wait until they hit 20M, as it has more of an impact from a marketing POV than coming out and announcing figures every 5 million units sold.

By the end of this year I think PS4 will have sold 20M at least, if not 21-22M, but I guess we'll see.

Think about it this way. At the end of September they had shipped 13.5 million.  They probably had under 500k on shelves.  14,088,511 sold through is probably at the end of October.  Just add November's numbers and (about 2.5 million) 1 week of December and you are pushing above 17.5 million easy. Xbox One has to be at 9.4 at the very least and Wii U is simply overtracked for posterity. 

They wont, the number shown was definitely since September/October (you can just do a simple math based on Shawn Laydens infographic around destinys launch). The console would probably hit 20m by the end of december/january, its in Dec/Jan NPD where sony would give an official announcement of 20m sold (if they even want to). You cant expect them to be announcing for every million sold, not only would it be tiring but we would start seeing "Sony arrogance" threads and unnecessary gloat articles

i couldn't have said it any better. I think 22M is a stretch but 20M sold to consumers by Jan 1st is very realistic. Higher than 21M I just can't see it but won't deny it's possible. January numbers will be inflated with the China launch as well so they will hit the ground running. Just one thing. We believe VGchartz has it laregely under tracked but we need to minus the over track from November. Thanks to that they are not as far behind as they would be. 

PS4 is actually going to more than double Wii U lifetime sales in just over 1 year. Incredible. I think you paint a pretty picture so if we guessed 17.5M by the end of November it should be over 19M by this very day. That would leave it at round 20M by the end of this week and by Jan the 1st 21M. 

Why would they show the number from the end of October? I think this number is more likely their first year of sales, So November 15th.  However I could be wrong but why not just give the number for the year? Makes no sense at all, this would put them in a way better light woudn't ya think?  If in 2 more weeks they moved x amount more systems, then why show old numbers that are 2 weeks before the yearly milestone and also show them in a better light?

Good guess. I'll go with something similar but my final number between 20M and your number.
