IMHO, PS4 should remain a Cell based console.
Could Maybe use the multicore version of the Cell due to release in 2011-2012 : http://img411.imageshack.us/i/roadmap1kh0.png/#q=ibm%20cell%20roadmap
CELL BE at 3,8 GHz with 4 PPE and 32 SPE's 
A RSX Compatibility chip to allow every PS3 games to work with it
A Faster Blu-Ray Drive
2-3 Gigs of Ram
500 GB Hard Drive
Wifi
And the Price at Release : 400$ Max
