What they think that is and what would actually happen are two different things. Like did they expect 10 million and they got a 8 million seller? 

Also their own fault with things like 'you trained your fans to wait for sales' and 'um Ubisoft, you know people don't like you'.

Thanks for the information. Excluding November we aren't a crazy amount off. Looks to be about ~54K too low for PS5 from June to October and ~96K too high for Xbox Series. November though definitely the biggest amount off. PS5 about ~148K too low and XS ~294K too high. And yes, as always I will do adjustments. 

I guess there weren't any Switch leaks?

Edit: These adjustments look like it means our estimates will have Xbox Series a little bit below 10M for 2022. 

Nothing yet on Switch but they're asking him for it. lol 

I'll keep an eye on InstallBase and see if we get any Switch leaks. 

Funny that in is this website, numbers prediction are always too high for Xbox but too low for PlayStation... biased much ?

That isn't on purpose and not always true. In Holiday 2021 we overtracked PS5 by nearly 1 million. 

We are working on changes for 2023 that will hopefully make our initial estimates a bit more accurate. 

Not bias... it's expectations. The community here generally expected this generation to be much closer than the previous one, this extends to the tracking team. Xbox quarterly reports being more vague than before (due to the big price gap between Series S and X) is also making revenues less meaningful/reliable for extrapolation. Xbox sales are extremely difficult to accurately estimate, this is why I never take any estimates very seriously, can't even trust Famitsu's numbers for the matter. But I respect most relevant estimates because they represent a knowledgeable person's hard work, which does apply to VGChartz.

That said, the leak's November figures were a disaster for Xbox. They lend weight to a lot of arguments that I and some others made, but even I didn't think it was going to be this bad. Series S is looking more and more like a misfired product, Series X too might be misfired in the sense that it's very expensive/difficult to produce in true mass quantities. Series S was likely carried by the pandemic and the limited PS5 (and Series X) availability relative to demand.

Let's see what Starfield can do because Xbox is in serious need for a killer app right now. Then again, Xbox's biggest problem may be its redundancy to the millions of players who are switching to PC.

In the end, I was right to lower expectations for XBS for November. But I still underestimated PS5, Switch I think I got close.
