The new report from the Japanese press states that the PS4 will be on sale for or above the 40,000 Yen which is around 316 euros. This of course is the release price in Japan, and do not know exactly at which markup it will be on sale in Europe. The machine thou will be hitting the streets later this year or early next year as the report states.
Also possible multiple SKUs will be releasing meaning high-end models.
Rumors also say that the will be using the Gaikai streaming techonology and the Cell chip is also to get a boot. Who know's exactly what will come out. Let's wait for the much awaiting press conference from Sony this month to know more.
I guess we have to suffer until the 20th February 2013 to know more.
