Eurogamer writes: "Gran Turismo 5 Prologue appears to have missed its March 27th PlayStation Network launch date, with the game unavailable from Sony's PAL store at the time of writing.
Speculation grew as the day wore on with no new files that Sony was holding off until it was possible to include the new Grand Theft Auto IV trailer - the embargo on that was 10pm - but as the hour came and went still the storefront remained unchanged.
In fact, a big fat nothing has gone up on PSN overnight, despite us staying up until our eyes bled, and Sony hasn't said anything to the press yet, or on the European PS3 forums, where people are not very impressed."
