PS4 Pro sales #'s haven't been separated from PS4's total. Why would a Switch Pro be considered the end of liftetime Switch sales? If we are counting "Pro" sales separately, then I don't think PS4 base model has passed PS3 sales yet.
Possibly, but it wouldn't be too far off now either. I suspect PS4 Pro sales are around 7-10M by now (around a third of the PS4 consoles in the US right now are Pros, for instance), so if the base consoles haven't passed the bar yet, they will do so very soon.
