I originally had doubts about my purchase back in mid april this year, but after seeing the "upgrades" to the 15 inch pro I am glad I made my purchase and will never look back.
Being able to replace my battery and hdd with more ease than these new ones definitely suites me much more.
The processor upgrades are minimal, and IMHO I think the life of the computer is significantly reduced with processors like the 2.93 and 3.06... especially in the insanely-hot-already mbp.
I can see the price of the more "user configurable" pros going up definitely, had I not have purchased my mbp when I did I would have gone to ebay now and purchased a the previous pro definitely.
Just my thoughts.
