The PS2's architecture allows for much easier use of multiple CPU cores in emulation than the GC or Wii do, simply because the PS2 has all kinds of coprocessors, whereas the GC/Wii only have a CPU and a GPU (and the starlet, which we HLE anyway though). For the PS2, you "only" have to offload the emulation of one of the chips onto a separate thread, for Dolphin.. meh.
Dolphin already makes use of 3 CPU cores when both the GPU and the LLE DSP emulation run on their own thread, be happy with that.
