Even if it has been that way they still are not that new. Since they came out with the Unibodys, there has been new Mac Pro's, a new iMac, Mac Mini, 17-in MBP, iWork 09, iLife 09, and a new iPod Shuffle. So it is one of the oldest things in the store.
When the new iMacs came out, the Mid range MBP got a small processor speed bump. It used to be 2.53 not 2.66. They also added the BTO option of a 256 SSD to both 15" models
