That's insane. VGChartz is doing something outrageously wrong if they're undertracking consoles by over 80k in a single region.

It probably has something to do with the sporadic sales of Black Friday. Probably hard to figure out numbers and there is so much sales data to rumage through not only for VGChartz but for retailers.

Updated to November 24th with adjustments

 4,412,273 Vitas sold by end of 2012!

Vita Weekly Predicted Sales 12/22/2011 - 12/31/2012

Vita Lifetime Predicted Sales 12/22/2011 - 12/31/2012

As everyone probably knows, Vita had some undertracking for Black Friday week and while Sony announced 160,000 sold in the US, VGChartz has adjusted their number to 135,653. This could be a shipped vs sold difference or still be slightly off, but the benefit of the doubt goes to VGChartz. They might have made up the difference in their maths by readjusting weeks earlier in the month, I'm not sure how they do maths here, but over 20k more Vitas sold throughout the month of November due to adjustments. This pins Vita's install base at 3.55 million and the prediction now has it at 4.41 million since release and 3.93 million in 2012 alone.

While a world wide 200k Vita's this past week is not a bad number, it is below what should have been 230k after accounting for the adjustments of the week prior.The remaining weeks will be important for the system as an increase in word of mouth from new sales, holiday shopping lists, new deals, and higher discretionary spending should elevate sales above levels seen earlier this year. Will the Vita maintain its moment for December? Will that momentum enter into next year? Or will the system be roughing it again until that rumored price drop sometime in Spring, Summer, or Fall.

What momentum, Chark, Vita with your prediction still doesn't sell 4 million consoles in 2012, even when it sold acceptable numbers this black Friday, there is no momentum. Momentum means continuity in time, not one not so dark spot. Cut the PR crap, please, or at least formally apply for a job at Sony PR department.

Oh stop that. Here momentum:

The last seven weeks of Vita sales

The natural increase of Christmas and black Friday? Will you say the same next week with the decrease on unit sales? Momentum is what the 3DS has in Japan, or X360 and PS3 have, at least for now. Vita is fighting for it's survival, it has no momentum yet.

For someone trying to lecture me on momentum you aren't really doing a good job. Sales increase over time = momentum. Vita is having a little, does that bother you? Momentum isn't a relative property, speed is. You can argue 3DS selling more and you can show its had momentum for quite some time, but you can't say Vita isn't showing some momentum coming into the holiday season. The question is if it can maintain a higher level of sales that the 30-50k it was doing most of the year. If the Vita drops down to those levels next week, then yes you can say the momentum is dead or that it never existed but if it holds over what it had the month or two prior than yes it has momentum and it may transfer to better bottom line sales next year.

By your same definition, PSP, DS and Wii have momentum, but anyone sees the bullshit in your reasoning.

Whatever, Chark. I'm not emotionally invested in this console, or anyone. I'm tired of the PR and community managers wannabes like you, if you want to believe your PR work, so be it, but don't blatantly lie to others.

PSP has little to no momentum, maybe in Japan. Its sales haven't even doubled this holiday from what it has been selling for months and is selling around their spring average sales. The DS had a great week and a decent week before that but the rest of its sales are slacking. It seems to have momentum around the holidays but with such a isolated spike, even with the 90k week, it could just be a sales rush. The Wii did pick up momentum leading up to this holiday, more than the Vita, with steady inclines weeks in advance and did well for having its successor launch. The Vita has some momentum, some. It has had sales inclines for two months over its typical weeks.

Not emotionally invested? Sure you are. Here you are consistently addressing Vita's negative sales and dampening any positive outlook. That looks quite invested to me. You're one of my best posters!
