Yes, I'm a newbie first poster.
Even as a professional software developer, I really could not care less if there is a C2D. Neither I nor my team have current needs for 64 bit.
However, I have still postponed my upcoming MBP purchase in hopes of Apple's upgrades for other reasons. A (much) larger HD, single 1gb ram stick as minimum standard (has no one else asked for this?), and higher screen resolutions (here's hoping), and sure, some faster procs as well are worth my wait. Sure I'd still pump it up to 2gb, but it would be THAT much more inexpensive to do so. Apple seems to rarely bump ONLY the processor. And if that's all they do, it simply still won't be enough to keep them cost-competive on the hardware end.
And yes, I adore OS X (and apple hardware) and am willing to pay the understood premiums involed therein, but will only use it part of the time, as I'll be spending much time (sadly) working in Windows and Linux as well.
A 512mb baseline simply cannot be categorized as "Pro" any longer.
