I think Shademaster's table says more than I can, but yes, a 6 core 3.33 would be a good machine. If it makes it to the base level entry spec is, imo, doubtful, given that there is a $1000 worth chips in the 2.26 multi-core and only $300 in the quad right now - that's basically saying that Apple are going to eat $700 per 6 core base machine they sell?
Yeah, I doubt it as well, unless Apple raises prices. I can see Apple using the same quads as now in low-end and then 6-core in higher end
