[quote name='snowsquirrel']Maybe for backwards compatibility reasons. In fact, I read something to this effect about a year ago. That they wanted another cell, so dev's would have an easier time of knowledge transfer. The cell would be very hard to emulate on a non cell CPU, as it is a very different architecture.
On the other hand....
The cell remains expensive, and that is part of the reason they have had trouble dropping the price at a rate to keep pace with MS. Sony is probably one of the only people buying this chip now, so it doesn't get any cheaper for the manufacturer to make. If they were smart, they'd go with an simple architecture like the 360. Easy to develop for, and parts that drop in price, and are readily available, and easier/cheaper to manufacture. This would likely kill any change of b/c though... Still I'd rather keep my PS3, and have an affordable PS4, that is easy to develop for.

I'd rather they keep the cell processors. It'd be harder to develop for, sure, but I'd have better graphics and other things then the 360. I think developers who have made Ps3 exclusives, like Naughty Dog, know how to take advantage of them.
I hope they add IBMs newest cell, the PowerXCell 8i. Even though it's the last of its kind...which would probably make it more expensive.
