https://www.gamespot.com/articles/next-gen-playstation-system-will-launch-in-2018-an/1100-6449662/The wait for the next iteration of PlayStation may not be as far away as you expect, at least according to one analyst.
The Wall Street Journal reports that Macquarie Capital Securities analyst Damian Thong "said he expected Sony to release its next-generation PlayStation by the second half of 2018."
Analyst predictions don't always pan out, and this isn't necessarily based on some inside scoop. But the WSJ's reporter notes on Twitter that this is the same "analyst who correctly predicted PS4 Pro and Slim" ahead of their respective launches.
That certainly lends credence to the prediction, though in all likelihood, we won't receive any official word from Sony for quite some time. The PS4 was announced nine months prior to its release, while the PS4 Slim and PS4 Pro revisions were revealed just one week and two months, respectively, before they hit store shelves.
