PS3: THE FINAL FRONTIER//Orange Box用到了360九成功力以上

We can tell you that in terms of the whole game together on the PS3, we are not even using the SPU's and it is purely built on the graphics card and Cell. We're still optimizing for PS3 more because we can, which can explain the slight delay to you. But no worries, everything is going smoothly to put down any rumors.

看这段, 游戏没用到SPU, 只用了cell和图象卡.为了优化又可能延期了.
