Sony doesn't give out sales for every little thing, they announced sell through at the end of the year, and will this year too. They haven't mentioned Slim sales either. It was also the top selling sku on Amazon UK last time i was on there
Hate to tell you, but if you think Scorpio is going to do any better, you will be disappointed. Worldwide, it will sell less than the Pro. But whatever makes people feel better about 2:1
