It's not out and it's not announced – but retailer CEX is already offering to buy PS4 Slim consoles that are available in the wild.
Furthermore, it's willing to sell it for 380.
Not that CEX has any in stock at the moment, which isn't a huge surprise. But with the machine already available in very limited numbers in the market, it may only be a matter of time until the chain manages to lay its hands on a few units.
Could CEX land itself in potential trouble for selling the machine before it's even been announced? History suggests not.
