Japanese media claims Sony plans to use more affordable components for its next-generation PlayStation 4 console. PC Watch claims Sony will likely use a substantially improved version of the Cell processor with backward compatibility for PS3 games:
In order to maintain backwards compatibility and not to substantially shift the way of programming for the PlayStation 4, Sony intends to utilize substantially improved version of the Cell central processing unit (CPU), reports PC Watch web-site. The chip can potentially have as many as 24 or even 32 synergetic processing units, though, at this point actual specifications are hardly set by SCEI itself.
While Sony PlayStation 4 is years away, its developer already has a goal of making it more affordable than the predecessor in order to compete against the successor of Nintendo Wii, the most popular current-generation video game system, the web-site claims.
Considering the fact that PlayStation 3 already features technologies like Blu-ray optical drive, Cell processor, XDR memory and some other, it is very likely to expect the PS4 to sport them as well, but this time at a considerably lower price. This will also allow the next-generation video game console to take advantage of the PlayStation 3 infrastructure and heritage.
