Gameindustry.biz reports that Sony officials has confirmed that the Playstation 3 will feature a Blu-Ray disc drive, providing content developers with more than 20gb of storage. This is naturally very beneficial for Blu-Ray against the competing standard HD-DVD, as Playstations are products of very high volumes. PS3 alone will guarantee a potential content market of millions of Blu-Ray enabled players.
Single-layer Blu-Ray discs can store up to 27Gb on one layer of data, compared to 4.7Gb on DVDs, although the version of the standard favoured by Sony holds only 23Gb - still around five times larger than existing DVD discs. The Blu-Ray specification also allows for reading existing DVD discs, so the PS3 will almost certainly still be able to handle standard DVD movies and PS2 titles.Source: Gameindustry.biz
