People with the 2.93GHz Mac Pro's (or non-base) want/need as fast as is possible. e.g. in my case, if I had a 3.2GHz Pro, i would be able to get renders done at 14% higher resolution in the same time...and that's just better...or i could get them done in 12.5% shorter time...and that's also just better...why not have better?

My point being that although the 3.2Ghz would be nice to have I don't see it happening. And the 2.93Ghz is very fast capable machine holding off an upgrade on the very low chance Apple will update just doesn't seem worth it to me.
I have the 2.93Ghz Octo right now, if I had the choice I would have went with the 3.2Ghz myself. But for most people the .27Ghz speed bump will be almost unnoticeable for the price.
