"PS4 has now cumulatively sold through more than 73.6 million units globally as of December 31, 2017." (4 years, 1 month and 17 days).
Right now, Sony should double down on PS4/PS4 Pro - in my opinion, it has a clear chance of becoming the best selling console of all time.
Releasing PS5 in 2019 won't benefit them.
