ps2-wii: Wii has ~2x the memory, a GPU thought to be on par with the xbox, and a CPU thought to be ~50% faster than the gamecube
wii-ps360: ps360 has ~8 the memory, GPUs thought to be 1 or 2 generations ahead, and "multicore"-CPUs running at ~4x the speed of the Wii's single core.
Is the gap comparable? No. The problem for the ps360 is that HD graphics 'eat' into that memory/processor/GPU gap - but the Wii is closer in performance to the PS2 than it is to the ps360.
