An advert has appeared in what looks like a catalogue for French supermarket chain Carrefour, claiming the ’new’ PS3 will be €299 ($427).

The PS3 pictured is the current model, although it reads above the image: "New console, new price," and line of small print next to it saying "Visuel non contractuel", meaning "non-contractual image" - basically the picture may differ from the actual item, lending weight to speculation this ad is for the much-rumoured PS3 slim.

Speculation is high that Sony will announce the new machine at its press conference at Gamescom next Tuesday.
