Do you think there will ever be a MacBook Pro with Dual Core Processors? (I realize there are the Duo Core Processors.)
Thanks!

No because by the end of 2008 Intel's mobile quad-core will be out.

Why?
The cases where true dual processors are beneficial over a dual core processor, are for very high memory bandwidth problems (typically large scale serving or large HPC problems, i.e.- large scale simulations). These are not the type of problems that are suited well to a laptop.
Along with the higher memory bandwidth, you also use significantly more energy to drive a dual processor system, which makes them impractical for laptops.
So to answer your question- no, I dont think we'll ever see dual processors in a MBP. With the trend in mobile/consumer computing moving towards single physical CPUs, with multiple cores, you will probably, however start seeing quad+ cores in the MBP.

if you think the MBP's are running hot now...imagine dual MBP's

my macs: quicksilver dual 800 g4, 1.24 gig ram, 500 gig hd, 20 + 17 inch displays
(first mac i've ever owned, bought brand new)
2.16 core 2 duo macbook pro, 2.0 gig ram, 120 gig hd

It's not much difference to be honest and more expensive to implement. Multi-core is more cost efficient and as architecture improves memory bandwidth keeps going up.

In very specialized cases it can make enough of a difference to be worth the expense (i.e.- an embarrassingly parallel simulation, with no message passing between processes, with a large memory throughput- one of the sims I work on every day), but as I mentioned before- this would never be implemented on a laptop, and would be of no consequence in almost all cases.

Yeap, and imagine the battery life.

Core 2 Duo is a dual core processor... either I'm confused or the OP is.

The general opinion is that he meant dual processors (traditional SMP, each CPU on its own bus) but who knows until he tunes back in.
