* The Pro isn't selling like hotcakes either.
* Scorpio and the Pro don't need to compete in price, they are not high-volume hardware. They are Halo products to draw attention to the platform as a whole, the bulk of the sales will continue to be the Xbox One S and Playstation 4 Slim which will continue to be price competitive.

It's a few months old, but it seems to indicate otherwise.

Did you read the whole link? Translation error most likely, especially in the context of what they were talking about.
Pro beat its sales expectations more than slim's sales expectations is likely what was meant.

That indicates about 15% of total sales were for the pro, about 10% in Japan.
