When will the Switch pass 160M?

My fellow vgchartzerz, sony has confimed 160m in their anniversary site.
Also, they round down the nunbers, example 102m ps1, instead of 102.49, ps3 87 instead of 87.5,ps4 117 instead of 117.2
Hence,probably ps2 lifetime sales are exceeding considerably 160m.
What's boggling is that they dont show the psp sales, which was a great success (close to ps3) , to not extrapolate ps vita sales...

How did they confirm it though? By posting an ambiguous number on their site? I still dont understand how this is confirmation of anything.
