I understand what you're saying, but I think rumblpak is right about it being 64-bit. x86 is the architecture which most PCs have been using since the early days. It used to be 8086, 80186, 80286, 80386, 80486, etc, which is where x86 comes from. Eventually Intel changed to brand naming, but the processors are still based on the original 8086 (even the latest i7s).
x64 does typically refer to x86-64, which is a 64-bit extension of the x86 platform (one of many extensions). Sony could just as well have said that, however it's basically a given that it will be x86-64. We already know that the CPU and GPU will be on the same die from yesterday's presentation. The PS4 is rumoured (or is it official?) to be using AMD's GPU. That means we'll see a hybrid AMD CPU+GPU chip and if we look at today's offerings from AMD, you'll see they only manufacture x86-64 products. It wouldn't make sense for them to leave out the 64-bit instruction set.
One final thought. Intel does make a 64-bit only processor called Itanium. This processor requires specialized software to run on it as it is not compatible with x86 instructions, whereas x86-64 processors will happily run x86 32-bit code.
