Being 10x more powerful doesn't mean it can emulate the brute force of the single minded cell spe's
You can do more with an 8 core general purpsose cpu, yet you can't emulate the raw 3.2 ghz speed of the cell, no matter how many 1.6ghz cores you have. The Cell spe cores are single threaded, there's nothing to split up. You can alter the code and split it up yourself or use more efficient code instead of using the limited instruction set of the Cell. However an emulator can't do that. It can't know where to split the instruction sets and run them parallel on different cores.
It's not impossible. Building a compiler that converts the code running on the cell to something that can run on one or more slower processors is a possibility. One that will require a lot of time and resources. Sony certainly didn't think that was worth the trouble since they're using actual ps3 hardware for ps now. It's actually 8 ps3s shrunk onto one board. It would be cool to have one of those super ps3s at home :) Lan party in a box.

While I don't think a PS3 emulator is very likely on PS4, doesn't the three cores in Xenon present the same problem? Actually the architecture of both CPU's isn't that different (generally) from what I gather.

The Xenon cores each have 2 hardware threads sharing the available 3.2 ghz. The 6 hardware threads are spread over 6 1.75ghz cores of the XBox One. The cell is just weird with one 2 way threaded ppe (similar to 1 Xenon core) and 7 additional single threaded sattelite processors (spe).
