While there are many rumours going around on the final PS3 price, it seems that a firm final price has not been put in place as of yet. No doubt it will be close to the Xbox 360 in price to compete in the market.
Gamespot with some interesting details:
With Microsoft announcing its worldwide pricing scheme for the Xbox 360, the onus is now on Sony Computer Entertainment to decide how much its PlayStation 3 will cost consumers.
However, SCE also needs to assure third-party publishers that its next-gen console will be affordable for a wide enough audience to ensure PS3 games will be profitable to make. Recently, Koei CEO Keiko Erikawa commented that her company would consider shifting to another platform if PS3 development proves too expensive. This is despite the fact the company is currently a big supporter of the PS3, announcing two new games at the 2005 Tokyo Game Show alone.
