C'mon Matt: it's because of thousands of miles of 70-80+ mph interstates, quieter running at cruise speed, and the push to return better highway mpg. Would I want to ride around in the Vette with a 4.10 rear end, in 4th gear instead of 6th? I wish our X had an OD or lower numerical axle...4 grand rpms at 80 in the X isn't my idea of engine maintenance.
