Same Here! No 10.6.7...doesnt even show up in software update. I called apple. they dont have any info on why. All the rep said is the new model might have any bug fixed and so it doesnt need 10.6.7...

I managed to get Portal 2 working on my new 27" iMac by editing a system file to fool Steam into believing that you are running 10.6.7 - I believe the 10.6.7 requirement is because of new ATI graphics drivers that were bundled with that release and therefore this is quite safe (as the 10.6.6 build on the new iMacs obviously has the drivers for the machine).
I've posted the full details at http://bendodson.com/weblog/2011/05/04/portal-2-on-the-new-imac-10-6-6/ but basically you need to change the SystemVersion.plist file in your /System/Library/CoreServices/ directory so that the two references to 10.6.6 are changed to 10.6.7 - Steam will still complain but when you say "continue anyway" it'll actually run.
