Actually, the price drop happened on 9th July, so there was 5 days of the $499 price and only 2 days at the original $599 price, so you're theory gets smacked on the face straight away.
Yes, the sales were down 13%...it was to be expected.
Prediction (June 12th 2017)
Permanent pricedrop for both PS4 Slim and PS4 Pro in October.
PS4 Slim $249 (October 2017)
PS4 Pro $349 (October 2017)
