Due to the relative age of the AppleInsider article, I'd say its pretty safe to assume that the MB/MBP expected upgrades are only chip swaps. According to the article, the laptop line is done being engineered completely....its all marketing timing at this point. I doubt there was enough time for a full redesign based around the C2D chips. Marketing will pull the trigger based on current sales, ending any current promotions, and best timing for the holiday.....thats it. The CD and C2D lines are both far too new, and CD isn't exactly being dropped in favor of C2D en masse industry-wide, to worry about any "reputation" issues for a few months. 10/10 is a good guess based on current shipping times, inventory, blah blah blah....but anytime in the next 4 weeks would be plenty plausible. So, I predict when the C2D MB/MBPs are released, we are going to see a slew of threads of guilt-filled CD MB/MBP owners who "should have waited," even more angst-filled "Apple sucks so bad, they didn't make 4gb ram, 10k rpm drives, and the latest nVidia Quadro card standard!!!!" type posts, and plenty of people throwing down plastic while Apple rakes in the dough. For me, I only hope my dying PowerBook G4 lives long enough to C2D MBs. If it doesn't, oh well....I'll buy a CD MB and be happy, knowing that the moderate amount of media encoding I do is the only thing I'll be missing out on with reasonably measurable performance increase over CD.
