(Wii, cpu, gpu)When will Broadway and Hollywood get a die shrink?

[StarcraftManiac]

Nintendo never gave any data about how powerfull the GPU and CPU of the Wii are (somewhere it states 733Mhz and something else but that info isn't from Nintendo...)

So, Nintendo could have put in new chips without letting the world know Or, since it's a modified Gamecube chipset they are already at 45Nm
