I'm not sure either if PCs will provide this functionallity. But it's not due to lack of transistors. The main reasons would be lack of imagination, lack of remaining bits in the opcodes (especially for X86) and limited bandwidth and out-of-order capability on the memory access pipelines. Current micro chips have huge numbers of transistors and a Cray style vector unit would easily fit on a small corner of these chips.
