To those who have been waiting to upgrade their hard drives until the Hitachi Travelstar 7K500 hit retail in the US, wait no more. Fry's has the retail version in-stock for $89.99. I just purchased one for my MacBook Pro and should hopefully have it by the weekend for testing. Interestingly enough, Hitachi quotes lower power consumption under certain circumstances for the 7K500 than for the 5K320 that I currently own, so perhaps there will be a slight improvement in battery life as well, although it's not a point of concern.

Edit 11/24: Newegg also stocks the drive now, for $79.99 with free shipping at the time of this post. http://www.newegg.com/Product/Product.aspx?Item=N82E16822145275&Tpk=travelstar

Update 11/20/09:
I had some time today to install the drive, restore my system from a Time Machine backup, and benchmark it. The only problem that I ran into was Software Update crashing when I tried to open it, but reinstalling the 10.6.2 update fixed that. Surprisingly, the new drive is actually quieter and vibrates less than the 5K320 that it's replacing. My virtual machines resume from a suspended state much more quickly, and overall the system feels a little bit faster. Here's the Xbench results for both the old drive and the new one:
