The redesigned console is expected to be shown at Tokyo Game Show this week, according to an advertisement spotted by Polygamia.pl (translated by The Sixth Axis).
It will be released in Poland on September 28, which is expected to be a European-wide release date.
Two versions of the new slim system will be made available; a 12GB SSD version retailing for €199 (£161) and a 500GB model for €299 (£241).
Rumoured for gamescom, detail and images of the console, which features a sliding panel housing a top-loading disc drive, appeared earlier this year.
The first rumors of a more compact PS3 emerged after documents that Sony filed with the Federal Communications Commission appeared to show a smaller, slimmer iteration of the console.
Sony is yet to officially announce plans to release a new PS3 model.
