The game will, however, be "shipped on a singe disc".
The Angry pixel reports that the rumoured two-disc set for Microsoft's Forza Motorsport 3 isn't true and we can expect a full reveal on the game soon.
The information comes from a source at Dhruva Interactive, an Indian game development company who has previously worked on 3D assets for titles including both Forza games and the previous two PGR titles.
According to the source Dhruva Interactive is already working on assets for the third game in the Forza series and claims we'll get a full reveal "fairly soon", presumably at E3 2008 next month.
The Angry Pixel also questioned the source on the rumour that Forza 3 will ship on two discs, by account of the game including so many cars and tracks.
"... one way or the other, the core game will be shipped on a single disc. Content won't be sacrificed... fans will be pleasantly surprised for what's in store," said the source.
Look out for more on Forza Motorsport 3 over the coming months.
