These problems may be a few years out, though. IBM has not announced when it will release the final chip, but the Cell project was originally envisioned as taking five years, suggesting that the final product may not be ready until as late as 2007. Although Sony refuses to talk about its future plans for the chip, it does admit that the Cell chip will not be the CPU in the Playstation3, reportedly slated for release in 2005.
