iMacs will see quads before MacBook Pros. Mac Pros will see dual octos (or dual six cores) before iMacs see quads.

Quads have been available to put in the iMac for ages. It's just another artificial limitation Apple has put in place on the iMac, again.
 
You'll have to wait until the Arrandale processors are released which is due around March 2010, although going on Apples previous track record with Intel, Apple should get them around early February, before I would have said in time for Macworld, but obviously since Apple doesn't attend that anymore thats unlikely. I'd still get a Core 2 Duo though until about October 2010 simply to maximise value because otherwise your getting the worst of a new thing if that makes sense.

Also to people who are saying the iMac's will get Quads before the Macbook Pro's, no they wont, the iMac is at the bottom of the food chain along with the 13" Macbook before it became the 13" Macbook Pro which it really isn't because it isn't a Pro machine.
 
An Arrandale Chip with high clockspeed and hyperthreading in January 2010 is about the closest thing to a quadcore portable that we can expect.

Without having proof my guesstimate is that for the average customer the difference between an Arrandale and a real quadcore will be negligible.
 
Apple has never gotten laptop processors early. They have only ever gotten Xeons early.

I thought they have an agreement now to supply them chips earlier than Apples competitors in return for exclusivity after the G processor days.

If you think about it, the Xeon is the truly new chip to come out from Intel since Apple made the switch, everything else was either out or in late development/production, regardless of platform.
