This unconfirmed news comes via an article which mainly focuses on Nintendo’s year-one sales forecast for the Switch.
The comment about the PS4 is offhandedly mentioned in Taiwan’s DigiTimes newspaper, which according to PlayStation Lifestyle mainly focuses on electronics and the region’s IT industry.
The story in question mentions the following:
Microsoft is also planning to release a new Xbox game console codenamed Project Scorpio and the product is expected to be announced at the E3 2017 event, targeting the year-end holiday season. Sony is expected to release a thinner version of its PlayStation 4.
While unconfirmed so far, we certainly rule out the possibility, especially given that the PS3 had several revisions during its lengthy lifetime.
