X2 went to mass production. I don't think they were using final units in that show so no worries. if they were using final units then...
another thing; X2 is using liquid cooling, how can heat be a real problem then? in any case, I don't think X2 consoles will over heat. that is a serious problem MS would not want to make in these very touchy times. they would never hear the end of it even after the PS3 launches.
