It is always the best policy to tell the truth, unless, of course, you are an exceptionally good liar - Jerome K. Jerome
In an official statement, Sony said the decision to revise the launch date was taken following "the delay in the mass production schedule of the blue laser diode within the Sony Group, thus affecting the timely procurement of key components to be utilised in PlayStation 3."
Rumours of a shortage emerged a few days ago, with reports suggesting that Sony had suspended shipment of the diodes to customers making standalone Blu-Ray players, in an attempt to keep production of the PS3's Blu-Ray drive running smoothly.
This is further bad news for Sony, coming so soon before the expected launch date, who have already received much negative press concerning the Playstation 3 console due to its huge cost, bundled Blu-Ray drive and costly proprietary components. µ
