If you go back and read the press release again you'll see that the '05 has express up AND down on both windows.
In addition if you hold the unlock button down on the remote both door will unlock and both windows will roll down! Great for getting the hot air out quickly in the summer.

You can close both windows and lock both doors by inserting the key in the driver's door and holding the the key in the lock position.

Unfortunately the lawyers won't let you roll up the windows from the remote.
The 99-04 Mustang has express down only and only on the driver's window.
My Lincoln LS has express up - down on both front windows and the global open (4 doors, 4 windows + moonroff). They are those nice features that once you have them, you can't do without them.
