Basically Christopher Dring just tweeted that PS4 this year is over 1m sales (as of last week), and "well above" 6m total now in the UK.
After last weekend, PS4 sales for the 2018 sailed past 1m in the UK. Which means the console has now sold well over 6m in the market in 5 years.

Currently VGC has the PS4 in the UK at 5.5m as of november 3rd.
( well above 6m, has to be atleast 6.2m right? PS4 is undertracked on VGC for the UK )
