Yet more news reaches us this afternoon from depths of yesterday's E3 briefing, informing us that 5 Prologue will be heading to the PlayStation Network before the year is out.

The teaser game will offer a free preview of what Polyhony's final GT5 opus will deliver, the game also giving us a first taste of action. Visually, the Prologue will resemble what envisage the final game to look like, in a word: stunning.

GT5 Prologue is the second product from Polyphony in 'anticipation' of Gran Turismo 5, the first being GT HD Concept, also available for free and also giving us a taster of what's in store. Phil Harrison tells us that the first Cencept title was downloaded more than one-million times, prompting this second taster from the company.

More soon.
