Well, it looks like the rumors were true, future Macs will infact feature Intel processors, starting in January 2006. Apparently a secret project deep within Apple has had every version of OX X running on Intel powered machines since the beginning.
I'm sure many folks will now think that a future version of OS X will run on an off the shelf PC, but I highly doubt that will ever happen. It also isn't clear on exactly which Intel processor will power future Macs, and if the x86 exploits that are so prevalent will be an issues for these Macs. Many details are still up in the air, but this is incredible news, and it's going to take time to sink in and get my brain wrapped around this whole issue.
