LOL, you have short term memory loss. Let's go back to Jan 1 of this year and look at a Macrumors MacWorld roundup:
Appleinsider has been the most vocal about the release of updated PowerMacs at MacWorld San Francisco. A December 4th report claimed that speeds of 2GHz, 2.2GHz, 2.4GHz and 2.6GHz processors were currently being produced by IBM with expectations of the release of new PowerMacs at MacWorld SF 2004. Later, "collaborating information" from the same site claimed PowerMac (and Xserve) updates with speeds up to 2.4GHz would indeed be coming at MacWorld SF 2004.

So, looks like u lost your shirt back in January

(you seem like the type to buy into this). Be prepared again with your 3.0GHz prediction.
If Apple was capable of even 2.2GHz up until now, even in Feb, March, or April, don't you think it would have happened? Yes, it would have. So I contend, since no updates of even 2.2GHz have happened by now, don't think the new product line will go 2.2/2.4/2.6 with 3.0 also available a few month later. IT AIN'T GONNA HAPPEN!
Remember, only the 1.6GHz is discounted. If the base was going to be 2.2GHz, we'd see the whole current product line discounted.
Sorry to be the voice of reason and to burst some people's bubble, but I hate to see such naivete.
