32bit code can sometimes be faster than 64bit code because 32bit pointers are smaller, use less RAM and put less pressure on the cache. It'd be interesting if Sony choose to run the processor in 32bit mode for that reason, they could also use something like the Linux x32 ABI (i.e. use the AMD64 instruction set but with 32bit pointers). Of course referring to the processor architecture as "x86" doesn't mean anything in that regard.
