Gran Turismo 5 Prologue will be coming to the PlayStation Network later this year, Sony announced at its E3 conference yesterday evening.

It's another free taster of what we can expect from the full Polyphony Digital game due some point in the future. The demo will let players race online for the first time ever in the series, using a bunch of shiny cars.

We imagine you'll probably be gawking at the hugely impressive graphics we saw in the on-stage trailer, too. "Look at the reflections on that," said Ellie Gibson, who was commentating live from the event.

The decision to release another Gran Turismo 5 teaser stemmed from the success of HD Concept earlier in the year, which let you race a handful of cars around a single track - supposedly powered by a version of the GT5 engine.

It was so popular more than one million of you clamoured to download it, according to Sony Worldwide Studios boss Phil Harrison. And rightly so, reckoned Eurogamer hack Tom Bramwell, who went hands-on with it back in March.

So it all seems to be shaping up well for the iconic and immensely popular racing series. But will we see the full game before 2009, Sony?
