I am wondering the same thing and have been since they announced that the '07 would have it. I feel it's the most glaring omission on the '06 and the only new feature that makes the '07 more appealing. Because the memory seat switches are on the seat itself (and not on the door or dash like most others I've seen) you would think that it's just a simple module of sorts that can be spliced into the '06 driver's seat wiring. I guess we'd have to compare wiring schemes on both model years.
Here's hoping...Joe
